This takes memory usage from 5.1GB to 970MB - it could go further by
using a small size of 2 instead of the default of 4, but given the
rather high cost of going over this limit by much, I figured a little
slosh would be worth the ~130MB of memory usage.
& this'll might not be such a big deal if we use a custom slab allocator
for the DenseMaps here anyway
While the vast majority (99.9%) of records use only 1 entry, the tuning
parameter to SmallDenseMap is the the number of buckets, not the number
of entries - so a small size of 1 wasn't useful, even for 1 element, it
would tip over into allocating (much, 64 slots worth) more space - none
of them ended up small.

Haiku uses GNU ld for linking, but is not captured in the
conditional when setting LIB_NAMES. This causes a shared
library with no symbols on Haiku. This patch simply adds
a check for whether the CMake system name is Haiku in
addition to the existing checks.

This is a follow up for one of
the previous diffs https://reviews.llvm.org/D32328.
getTypeSize and with getIntWidth are not equivalent for bool
(see https://clang.llvm.org/doxygen/ASTContext_8cpp_source.html#l08444),
this causes a number of issues
(for instance, if APint X representing a bool is created
with the wrong bit width then X is not comparable against Min/Max
(because of the different bit width), that results in crashes
(triggered asserts) inside assume* methods),
for examples see the newly added test cases.

I didn't commit clang-import-test.cpp in r307600, but it had some

Corrected that now.

- eliminated error handling for the indirect CompilerInstance, which should
never generate an error as it is created;
- added a new test for direct importation; and
- removed an unused implementation of the CompleteType() API.
This brings clang-import-test.cpp and ExternalASTMerge.cpp back to 100%
coverage on all metrics measured by DLLVM_BUILD_INSTRUMENTED_COVERAGE.

This is part of the continuing effort to increase parity between
LLD and MSVC PDBs. link still doesn't like our PDBs, so the most
obvious thing to check was whether adding an empty publics stream
would get it to do something else. It still fails in the same way
but at least this removes one more variable from the equation.
The next logical step would be to try creating an empty globals
stream.

This unit test constructed some profile records incorrectly. One of the
records had a duplicate name: adding that record into the writer caused
an error unrelated to what needed to be tested.

lld-link is apparently a symlink to lld. Our pdb writing code
uses llvm::sys::fs::getMainExecutable() and writes that value
into the PDB, which will resolve symlinks etc. But what we
really want is the exact value of argv[0], which matches what
the MS linker does. Fix this by just writing argv[0] instead
of calling getMainExecutable.

Reverting as it breaks tramp3d-v4 in the llvm test-suite. I added some

Summary:
As metioned in https://reviews.llvm.org/D34576, checkings in
`collectConstantCandidates` can be replaced by using
`llvm::canReplaceOperandWithVariable`.
The only special case is that `collectConstantCandidates` return false for
all `IntrinsicInst` but it is safe for us to collect constant candidates from
`IntrinsicInst`.

When providing the option "-polly-ast-print-accesses" Polly also prints the
memory accesses that are generated:
#pragma known-parallel
for (int c0 = 0; c0 <= 1023; c0 += 4)
#pragma simd
for (int c1 = c0; c1 <= c0 + 3; c1 += 1)
Stmt_for_body(
/* read */ &MemRef_B[0]
/* write */ MemRef_A[c1]
);
This makes writing and debugging memory layout transformations easier.

An instruction that has an immediate operand can't reach
this point. This is only called for a freshly shrunk instruction,
which prevously couldn't have had a literal constant operand.
This was also not conservative enough since it woudl also have
had to filter other constant-like inputs like frame indexes.

Many of the test cases in the runtimes require LLVM's testing tools, to
facilitate this working as expected we need to have all the test targets
in the runtimes depend on all LLVM testing tools used in the runtimes.

This was originally reverted because of two issues.
1) Printing ANSI color escape codes even when outputting to
a file
2) Module name comparisons were failing when comparing a PDB
generated on one machine to a PDB generated on another
machine.
I attempted to fix#2 by adding command line options which let
you specify prefixes to strip from the beginning of embedded
paths, which effectively lets us specify a path to "base" each
PDB from and only compare the parts under the base. But this is
tricky because PDB paths always use Windows path syntax, even
when they are created on non-Windows hosts. A problem still
existed when constructing the prefix to strip, where we were
accidentally using a host-specific path separator instead of
a Windows path separator.
This resubmission fixes the issue on Linux (and I have verified
that the test now passes on Linux).
