Summary:
Android doesn't intercept sigfillset, so REAL(sigfillset) is null.
And we can use internal_sigfillset() for all cases.

Save the integer type when diffing integers in template type diffing. When
integers are different sizes, print out the type along with the integer value.
Also with the type information, print true and false instead of 1 and 0 for
boolean values.

This method has no callers.
Also remove X86ELFRelocationInfo.cpp and X86MachORelocationInfo.cpp
which only existed to provide an implementation of that method.
Ok'd by Rafael and Jim.

Yet another wave of buildbot failures (though fewer this time).
I'm only reverting the Verifier changes, as the test cases
will be fine without them as well, and touching them as often
just introduces unnecessary churn.

If available, use the canonical template argument to fill in information for
template type diffing instead of attempting to special case and evaluate Expr's
for the value. Since those are the values used in template instantiation,
we don't have to worry about difference between our evaluator and theirs. Also
move the nullptr template arguments from DiffKind::Expression to
DiffKind::Declaration and allow DiffKind::Declaration to set an Expr. The only
effect that should result is that a named nullptr will show up as
'ptr aka nullptr' in diagnostics.

1) It was forward declaring functions without 'extern "C"'. That used to work
but only because of another bug in how we passes symbol only function names to the
compiler and stopped working recently.
2) These forward declarations were in the body of the User Expression, and they actually
need to go in the prefix file.

ISL 0.16 will change how sets are printed which breaks 117 unit tests
that text-compare printed sets. This patch re-formats most of these unit
tests using a script and small manual editing on top of that. When
actually updating ISL, most work is done by just re-running the script
to adapt to the changed output.
Some tests that compare IR and tests with single CHECK-lines that can be
easily updated manually are not included here.
The re-format script will also be committed afterwards. The per-test
formatter invocation command lines options will not be added in the near
future because it is ad hoc and would overwrite the manual edits.
Ideally it also shouldn't be required anymore because ISL's set printing
has become more stable in 0.16.

I originally reapplied this in 257550, but had to revert again due to bot
breakage. The only change in this version is to allow either the TypeSize
or the TypeAllocSize of the variable to be the one represented in debug info
(hopefully in the future we can figure out how to encode the difference).
Additionally, several bot failures following r257550, were due to
optimizer bugs now fixed in r257787 and r257795.
r257550 commit message was:
```
The follow extra changes were made to test cases:
Manually making the variable be the actual type instead of a pointer
to avoid pointer-size differences in generic code:
LLVM :: DebugInfo/Generic/2010-03-24-MemberFn.ll
LLVM :: DebugInfo/Generic/2010-04-06-NestedFnDbgInfo.ll
LLVM :: DebugInfo/Generic/2010-05-03-DisableFramePtr.ll
LLVM :: DebugInfo/Generic/varargs.ll
Delete sizing information from debug info for the same reason
(but the presence of the pointer was important to the test case):
LLVM :: DebugInfo/Generic/restrict.ll
LLVM :: DebugInfo/Generic/tu-composite.ll
LLVM :: Linker/type-unique-type-array-a.ll
LLVM :: Linker/type-unique-simple2.ll
Fixing an incorrect DW_OP_deref
LLVM :: DebugInfo/Generic/2010-05-03-OriginDIE.ll
Fixing a missing DW_OP_deref
LLVM :: DebugInfo/Generic/incorrect-variable-debugloc.ll
Additionally, clang should no longer complain during bootstrap should no
longer happen after r257534.
The original commit message was:
``
Summary:
Teach the Verifier to make sure that the storage size given to llvm.dbg.declare
or the value size given to llvm.dbg.value agree with what is declared in
DebugInfo. This is implicitly assumed in a number of passes (e.g. in SROA).
Additionally this catches a number of common mistakes, such as passing a
pointer when a value was intended or vice versa.
One complication comes from stack coloring which modifies the original IR when
it merges allocas in order to make sure that if AA falls back to the IR it gets
the correct result. However, given this new invariant, indiscriminately
replacing one alloca by a different (differently sized one) is no longer valid.
Fix this by just undefing out any use of the alloca in a dbg.declare in this
case.
Additionally, I had to fix a number of test cases. Of particular note:
- I regenerated dbg-changes-codegen-branch-folding.ll from the given source as
it was affected by the bug fixed in r256077
- two-cus-from-same-file.ll was changed to avoid having a variable-typed debug
variable as that would depend on the target, even though this test is
supposed to be generic
- I had to manually declared size/align for reference type. See also the
discussion for D14275/r253186.
- fpstack-debuginstr-kill.ll required changing `double` to `long double`
- most others were just a question of adding OP_deref

Summary: Since you cannot call finalizeObject manually through the C-API and other functions from the C-API automatically call it, LLVMRunStaticConstructors should also call it or otherwise you cannot call it without first calling a workaround function (or call any other function from the C-API which implicitly finalizes the object).

Value, type, and instantiation dependence were not being handled
correctly for CUDAKernelCallExpr AST nodes. As a result, if an
undeclared identifier was used in the triple-angle-bracket kernel call
configuration, there would be no error during parsing, and there would
be a crash during code gen. This patch makes sure that an error will be
issued during parsing in this case, just as there would be for any other
use of an undeclared identifier in C++.

Modify the TSTiterator to have two internal iterators, which will walk

This patch makes use of the handleLoadedFile hook added in r257814.
That method is used to check the arch and the OS of the files we are linking
against the arch and OS on the context.
The first test to use this ensures that we do not try to combine i386 Mac OS code
with i386 simulator code.

The release builds are configured to be reproducible, so that the
binaries compare equal between bootstrap iterations. The OpenMP
run-time build was failing like this:
runtime/src/kmp_version.c:108:79: error: expansion of date or time macro is not reproducible [-Werror,-Wdate-time]
char const __kmp_version_build_time[] = KMP_VERSION_PREFIX "build time: " __DATE__ " " __TIME__;
Figuring as the build currently doesn't set LIBOMP_DATE, it's probably
OK to skip setting the build time here too.

1) Instead of using pairs of From/To* fields, combine fields into a struct
TemplateArgInfo and have two in each DiffNode.
2) Use default initialization in DiffNode so that the constructor shows the
only field that is initialized differently on construction.
3) Use Set and Get functions per each DiffKind to make sure all fields for the
diff is set. In one case, the Expr fields were not set.
4) Don't print boolean literals for boolean template arguments. This prevents
printing 'false aka 0'
Only #3 has a functional change, which is reflected in the test change.

Summary:
Before this the Verifier didn't complain if the GlobalVariable
referenced from a DIGlobalVariable was not in fact in the correct
module (it would crash while writing bitcode though). Fix this by
always checking parantage of GlobalValues while walking constant

visit the constant it contains.

If your program refers to modules (as indicated in DWARF) we will now try to
load these modules and give you access to their types in expressions. This used
to be gated by a setting ("settings set target.auto-import-clang-modules true")
but that setting defaulted to false. Now it defaults to true -- but you can
disable it by toggling the setting to false.

Summary:
Previously we compiled CUDA device code to PTX assembly and embedded
that asm as text in our host binary. Now we compile to PTX assembly and
then invoke ptxas to assemble the PTX into a cubin file. We gather the
ptx and cubin files for each of our --cuda-gpu-archs and combine them
using fatbinary, and then embed that into the host binary.
Adds two new command-line flags, -Xcuda_ptxas and -Xcuda_fatbinary,
which pass args down to the external tools.
