llvm-objdump when printing the Mach Header to print the unknown
cputype and cpusubtype fields as decimal instead of not printing
them at all. And change the test to check for that.

Originally this change was causing failures on windows buildbots.
But those problems were fixed in r258806.

This patch was originally committed as r257885, but was reverted due to windows
failures. The cause of these failures has been fixed under r258677, hence
re-committing the original patch.

but to return object_error::parse_failed. Then made the code in llvm-nm
do for Mach-O files what is done in the darwin native tools which is to
print "bad string index" for bad string indexes. Updated the error message
in the llvm-objdump test, and added tests to show llvm-nm prints
"bad string index" and a test to print the actual bad string index value
which in this case is 0xfe000002 when printing the fields as raw hex.

but to return object_error::parse_failed. Then made the code in llvm-nm
do for Mach-O files what is done in the darwin native tools which is to
print "(?,?)" or just "s" for bad section indexes. Also added a test to show
it prints the bad section index of "42" when printing the fields as raw hex.

This patch adds the necessary plumbing to cmake to build the sources related to
GlobalISel.
To build the sources related to GlobalISel, we need to add -DBUILD_GLOBAL_ISEL=ON.
By default, this is OFF, thus GlobalISel sources will not impact people that do
not explicitly opt-in.

Some architecture specific ELF section flags might have the same value
(for example SHF_X86_64_LARGE and SHF_HEX_GPREL) and we have to check
machine architectures to select an appropriate set of possible flags.
The patch selects architecture specific flags into separate arrays
`ElfxxxSectionFlags` and combines `ElfSectionFlags` and `ElfxxxSectionFlags`
before pass to the `StreamWriter::printFlags()` method.

This addresses PR26060 where function lto_module_create() could return nullptr
but lto_get_error_message() returned an empty string.
The error() call after LTOModule::createFromFile() in llvm-lto is then removed
because any error from this function should go through the diagnostic handler in
llvm-lto which will exit the program. The error() call was added because this
previously did not happen when the file was non-existent. This is fixed by the
patch. (The situation that llvm-lto reports an error when the input file does
not exist is tested by llvm/tools/llvm-lto/error.ll).

Summary:
This is a re-commit of r257003, which was reverted,
along with the fixes from http://reviews.llvm.org/D15986.
r252532 added support for reporting the monolithic library
when LLVM_BUILD_LLVM_DYLIB is used. This would only be done
if the individual components were not found, and the dynamic
library is found.
This diff extends this as follows:
- If LLVM_LINK_LLVM_DYLIB is set, then prefer the shared
library, even if all component libraries exist.
- Two flags, --link-shared and --link-static are introduced
to provide explicit guidance. If --link-shared is passed
and the shared library does not exist, an error results.
Additionally, changed the expected shared library names from
(e.g.) LLVM-3.8.0 to LLVM-3.8. The former exists only in an
installation (and then only in CMake builds I think?), and not
in the build tree; this breaks usage of llvm-config during
builds, e.g. by llvm-go.

Summary:
Currently llvm::SplitModule as the first step globalizes all local objects, which might not be desirable in some scenarios.
This change adds a new flag to llvm::SplitModule that uses SCC approach to search for a balanced partition without the need to externalize symbols.
Such partition might not be possible or fully balanced for a given number of partitions, and is a function of the module properties (global/local dependencies within the module).

Follow up to r258001. These template functions might return both REL and RELA
relocations. The 'rel' noun looks less ambiguous.

introduce a new metric that is MaxInternalBlockCount which

This reverts commit r257751, bringing back r256105.
The problem the assert found was fixed in r257915.
Original commit message:
Assert that we have all use/users in the getters.
An error that is pretty easy to make is to use the lazy bitcode reader
and then do something like
if (V.use_empty())
The problem is that uses in unmaterialized functions are not accounted
for.
This patch adds asserts that all uses are known.

Added forgotten ELFDumper.cpp to commit.
Initial commit message:
[llvm-readobj] Add support for TLSDESC_PLT and TLSDESC_GOT dynamic section tags to the llvm-readobj.
If module uses uses lazy TLSDESC relocations it should define DT_TLSDESC_PLT and DT_TLSDESC_GOT entries.
They were unknown for llvm-readobj before this patch.
