[InstCombine] fold bitcasts around an extractelement (3rd try)
This is a redo of r255137 (reverted at r255227) which was a redo of
r255124 (reverted at r255126) with a fixed check for a scalar source
type and an added test for the failure that caused the revert.
Original commit message:
Example:
bitcast (extractelement (bitcast <2 x float> %X to <2 x i32>), 1) to float
--->
extractelement <2 x float> %X, i32 1
This is part of fixing PR25543:
https://llvm.org/bugs/show_bug.cgi?id=25543
The next step will be to generalize this fold:
trunc ( lshr ( bitcast X) ) -> extractelement (X)
Ie, I'm hoping to replace the existing transform of:
bitcast ( trunc ( lshr ( bitcast X)))
added by:
http://reviews.llvm.org/rL112232
with 2 less specific transforms to catch the case in the bug report.

Adding the modules to the global module list eleminate issues in the

Slit lib/Linker in two.
A linker normally has two stages: symbol resolution and "moving stuff".
In lib/Linker there is the complication of lazy linking some globals,
but it was still far more mixed than it needed to.
This splits the linker into a lower level IRMover and the linker proper.
The IRMover just takes a list of globals to move and a callback that
lets the user control what is lazy linked.

own symbol resolution to instruct IRMover what to do.

cases, we end up complaining about "atomic" mismatches between an
implicitly-atomic, readonly property and a nonatomic, readwrite
property, which doesn't make sense because "atomic" is essentially
irrelevant to readonly properties.
Therefore, suppress this diagnostic when the readonly property is
implicitly atomic. Fixes rdar://problem/
23803109.

[CMake] Provide options for toggling on and off various runtime libraries.
Summary:
Rather than having to add new "experimental" options each time someone wants to work on bringing a sanitizer to a new platform, this patch makes options for all of them.
The default values for the options are set by the platform checks that would have enabled them, but they can be overridden on or off.

Fix the target specific "-msse3" flag check in CMake. NFC
msse3 is a target dependent flag and must be guarded as check_cxx_compiler_flag()
checks only for compiler error messages and ignores warnings. Earlier COMPILER_RT_HAS_MSSE3_FLAG
is set to "TRUE" for all targets as clang emits warnings and the compilation spits unnecessary
warnings for non-X86 targets. This issue is fixed by coupling the flag with "-Werror"
