When there is a duplicate absolute symbol, LLD reports <internal>
instead of known object file name currently.
Patch fixes the issue.

If the CUDA toolkit is not installed to its default locations
in /usr/local/cuda, the user is forced to specify --cuda-path.
This is tedious and the driver can be smarter if well-known tools
(like ptxas) can already be found in the PATH environment variable.
Add option --cuda-path-ignore-env if the user wants to ignore
set environment variables. Also use it in the tests to make sure
the driver always finds the same CUDA installation, regardless
of the user's environment.

These were introduced in r323783 and use an X86 triple. I'll follow up
on the list to check if it would make more sense to remove the triple
and mark them REQUIRES: default_triple instead.

In this initial version we only GC symbols with `hidden` visibility since
other symbols we export to the embedder.
We could potentially modify this the future and only use symbols
explicitly passed via `--export` as GC roots.
This version of the code only does GC of data and code. GC for the
types section is coming soon.

Add a simple start entry point input file and have the tests
reference that rather than duplicating these.
This allows more tests to be pure `.test` files rather than
`.ll`.

When a the Apple link editor builds a kext bundle file type and the
value of the -miphoneos-version-min argument is significantly current
(like 11.0) then the (__TEXT,__text) section is changed to the
(__TEXT_EXEC,__text) section. So it would be nice for llvm-nm to
show symbols in that section with a type of T instead of the generic
type of S for some section other than text, data, etc.

"path" is too generic name for -L or --library-path because a lot of
linker options take paths as arguments. This change renames the option
to avoid confusion.

Initialize the default value of SymbolFileDWARF uuid with
the appropriately shifted DW_INVALID_OFFSET constant.
This change fixes the collision in the computation of DIE uid
(inside DIERef::GetUID) and incorrect CompileUnit lookup
(because of the misleading cu_offset value).

This change updates the Fuchsia-specific code to use the C++ friendly
duration expressions and flips on the building of
libclang_rt.fuzzer-x86_64.a and similar for Fuchsia. Given that
compiler-rt doesn't build on Fuchsia, test have been run by explicitly
building the library and linking it against
lib/fuzzer/tests/FuzzerUnittest.cpp.

Sometimes users do not specify data layout in LLVM assembly and let llc set the
data layout by target triple after loading the LLVM assembly.
Currently the parser checks alloca address space no matter whether the LLVM
assembly contains data layout definition, which causes false alarm since the
default data layout does not contain the correct alloca address space.
The parser also calls verifier to check debug info and updating invalid debug
info. Currently there is no way to let the verifier to check debug info only.
If the verifier finds non-debug-info issues the parser will fail.
For llc, the fix is to remove the check of alloca addr space in the parser and
disable updating debug info, and defer the updating of debug info and
verification to be after setting data layout of the IR by target.
For other llvm tools, since they do not override data layout by target but
instead can override data layout by a command line option, an argument for
overriding data layout is added to the parser. In cases where data layout
overriding is necessary for the parser, the data layout can be provided by
command line.

Strings which contain garbage data can trigger an exception in the XUnit
plugin at the UTF-8 decode step because the decode is strict. Use a lax
mode to avoid an exception.

Summary:
This is exposed during ThinLTO compilation, when we import an alias by
creating a clone of the aliasee. Without this fix the debug type is
unnecessarily cloned and we get a duplicate, undoing the uniquing.
Fixes PR36089.

Passing -minimize to dsymutil prevents the emission of .debug_inlines,
.debug_pubnames, and .debug_pubtypes in favor of the Apple accelerator
tables.
The actual check in the DWARF linker was added in r323655. This patch
simply enables it.

Without the patch !if() is only evaluated if it's used directly.
If it's passed through more than one level of class inheritance,
we end up with a reference to an anonymous record with unresolved
references to the original arguments !if may have used.
The root cause of the problem is that TernOpInit::isComplete()
was always returning false and that prevented use of the folded
value of !if() as an initializer for the record at the next level
of inheritance.

This patch is the result of a discussion on lldb-dev, see
http://lists.llvm.org/pipermail/lldb-dev/2018-January/013111.html for
background.
For each test (should be eventually: each test configuration) a
separate build directory is created and we execute
make VPATH=$srcdir/path/to/test -C $builddir/path/to/test -f $srcdir/path/to/test/Makefile -I $srcdir/path/to/test
In order to make this work all LLDB tests need to be updated to find
the executable in the test build directory, since CWD still points at
the test's source directory, which is a requirement for unittest2.
Although we have done extensive testing, I'm expecting that this first
attempt will break a few bots. Please DO NOT HESITATE TO REVERT this
patch in order to get the bots green again. We will likely have to
iterate on this some more.
