r243382 changed the behavior to always require a set of memchecks to be
passed to LoopVer.  This change restores the prior behavior as an
alternative to the new behavior.  This allows the checks to be
implicitly taken from the LAA object.

The fix for this is in LLVM but it depends on how clang handles the alias
attribute, so add a test to the clang tests to make sure everything works
together as expected.

r242520 was reverted in r244313 as the expected behaviour of the alias
attribute in C is that the alias has the same size as the aliasee. However
we can re-introduce adding the size on the alias when the aliasee does not,
from a source code or object perspective, exist as a discrete entity. This
happens when the aliasee is not a symbol, or when that symbol is private.

The version of libxml2 required by c-index-test must be at least 2.5.3. Considering that this version was released in 2003, you might think the check a bit ridiculous. Unfortunately, GnuWin32 ships with libxml2 2.4.12, which was released in 2001.

This allows us to have GnuWin32 on the PATH on Windows without causing compilation errors.

On Mach-O emitting aliases for the variables that make up a MergedGlobals
variable can cause problems when linking with dead stripping enabled so don't
do that, except for external variables where we must emit an alias.

removes a corner case in tests that don't set the diagnostic consumer.
In tests, it is good, not to set the diagnostic consumer so that Clang's
parsing diagnostics are still displayed in the test output and only
ClangTidy's output is analyzed differently.

On x86/x86_64 read only watchpoints aren't supported. Fall back
to read/write watchpoints in that case.

Note: Logic should be added to ignore the watchpoint hit when
occurred because of a write.

The ASAN callbacks are public symbols so we can search for them
with reading only the symbol table (not the debug info). Whit this

On android .oat files (compiled java code) don't have symbol
information but on SDK 23+ it can be generated by the oatdump tool
(based on the dex information).

This CL adds logic to download this information and store it in the

  While the compile time is not affected by this patch much it will
  allow us to look at all translated expressions after the SCoP is build
  in a convenient way. Additionally, bigger SCoPs or SCoPs with
  repeating complicated expressions might benefit from the cache later
  on.

  This change has three major advantages:
    - The ScopInfo becomes smaller.
    - It allows to use the SCEVAffinator from outside the ScopInfo.
    - A member object allows state which in turn allows e.g., caching.

  In order to find the llvm-obj directory it has to be (or a soft link
  to it) at one of the following locations:

    ${POLLY_SRC_DIR}/build
    ${POLLY_SRC_DIR}.build
    ${POLLY_SRC_DIR}-build
    s/${POLLY_SRC_DIR}/src/build

  Alternatively, the environment variable $POLLY_BIN_DIR can point to it.

As discussed in D11886, this patch moves the SSE/AVX vector blend folding to instcombiner from PerformINTRINSIC_WO_CHAINCombine (which allows us to remove this completely).

InstCombiner already had partial support for this, I just had to add support for zero (ConstantAggregateZero) masks and also the case where both selection inputs were the same (allowing us to ignore the mask).

I also moved all the relevant combine tests into InstCombine/blend_x86.ll
