c9736fba4b [llvm-pdbdump] Add include-only filters.
PDB files have a lot of noise in them, with hundreds (or thousands)
of symbols from system libraries and compiler generated types.  If
you're only looking for a specific type, this can be problematic.

This CL allows you to display *only* types, variables, or compilands
matching a particular pattern.  These filters can even be combined
with exclude filters.  Include-only filters are given priority, so
that first the set of items to display is limited only to those that
match the include filters, and then the set of exclude filters is
applied to those.  If there are no include filters specified, then
it means "display everything".

0ff0eb0687 [llvm-mc-fuzzer] Fix -jobs option.
The fuzzer argument parser will ignore all options starting with '--' so
operation mode options should begin with '--' and fuzzer options should begin
with '-'. Fuzzer arguments must still follow --fuzzer-args so that they escape
the parsing performed by the CommandLine library.

e59aef6de7 [llvm-mc-fuzzer] Support untested instruction discovery for variable length instruction sets like microMIPS.
Summary:
For fixed length instructions, we can use -max_len to limit the fuzzer to a
single instruction. This doesn't work for variable length instruction sets
since a 4-byte input could consist of one 4-byte instruction or two 2-byte
instructions.

This patch adds a --insn-limit to llvm-mc-fuzzer to limit the input in
terms of instructions processed.

3011017ecc Restore "Function bitcode index in Value Symbol Table and lazy reading support"
This reverts commit r247898 (which reverted r247894).

Patch fixed to address two issues exposed by buildbots:
- unused variable warning in NDEBUG mode
- std::initializer_list lifetime issue causing test failures

Original Summary:
Support for including the function bitcode indices in the Value Symbol
Table. This requires writing the VST after the function blocks, which in
turn requires a new VST forward declaration record encoding the offset of
the full VST (which is backpatched to contain the offset after the VST
is written).

This patch also enables the lazy function reader to use the new function
indices out of the VST. This support will be used by ThinLTO as well, which
will be in a follow on patch. Backwards compatibility with older bitcode
files is maintained.

A new test is also included.

The bitcode format (used for the lazy reader as well as the upcoming
ThinLTO patches) came out of discussions with Duncan and others and is
described here:

b0d872aece LTO: Disable extra verify runs in release builds
The verifier currently runs three times in LTO: (1) after parsing, (2)
at the beginning of the optimization pipeline, and (3) at the end of it.

The first run is important, since we're not sure where the bitcode comes
from and it's nice to validate it, but in release builds the extra runs
aren't appropriate.

This commit:
  - Allows these runs to be disabled in LTOCodeGenerator.
  - Adds command-line options to llvm-lto.
  - Adds command-line options to libLTO.dylib, and disables the verifier
    by default in release builds (based on NDEBUG).

This shaves about 3.5% off the runtime of ld64 when linking
verify-uselistorder with -flto -g.

9781f90c7e Re-commit r247683: Replace Triple with a new TargetTuple in MCTargetDesc/* and related. NFC.
Summary:
This is the first patch in the series to migrate Triple's (which are ambiguous)
to TargetTuple's (which aren't).

For the moment, TargetTuple simply passes all requests to the Triple object it
holds. Once it has replaced Triple, it will start to implement the interface in
a more suitable way.

This change makes some changes to the public C++ API. In particular,
InitMCSubtargetInfo(), createMCRelocationInfo(), and createMCSymbolizer()
now take TargetTuples instead of Triples. The other public C++ API's have
been left as-is for the moment to reduce patch size.

This commit also contains a trivial patch to clang to account for the C++ API
change. Thanks go to Pavel Labath for fixing LLDB for me.

97095fc404 [llvm-mc] Better error handling in ENOENT case + test.
This is a follow up to r247518.
As a general note, I think we could do a much better job testing for
error conditions in tools. I already anticipated in a previous mail,
but while implementing this I noticed that the code coverage we have 
for error checking is pretty low. I can arbitrarily remove checks from 
several tools and the suite still passes.

7ba3323aff Add a non-exiting diagnostic handler for LTO.
This is in order to give LTO clients a chance to do some clean-up before
terminating the process.

5f69f9fb81 [dsymutil] Discard useless location attributes.
When cloning the debug info for a function that hasn't been linked,
strip the DIEs from all location attributes that wouldn't contain any
meaningful information anyway.

This kind of situation can happen when a function got discarded by the
linker, but its debug information is still wanted in the final link
because it was marked as required as some other DIE dependency. The easiest
way to get into that situation is to have using directives. They get
linked unconditionally, but their targets might not always be present.

5571e7771e [dsymutil] Rename some variables NFC.
lldb doesn't like having variables named as an existing type. In order to
ease debugging, rename those variables to avoid that conflict.

24346ed19f [CMake] Add lto subdirectory explicitly.
This is required because ExternalProject_Add requires all targets specified in the DEPENDS argument must exist before calling ExternalProject_Add.

I have a follow-up patch to clang that enables using the just-built libLTO in bootstrap builds, so we need to be able to add the LTO target as a dependency in clang.

800a5b0664 llvm-config: Add --build-system option
Summary:
This can be used for distinguishing between cmake and autoconf builds.
Users may need this in order to handle inconsistencies between the
outputs of the two build systems.

793616c068 [llvm-readobj] MachO -- dump LinkerOptions load command.
Example output:

Linker Options {
  Size: 32
  Count: 2
  Strings [
    Value: -framework
    Value: Cocoa
  ]
}

There were only two tests using this -- so I converted them as part of
this commit rather than separately.
