Douglas Gregor 1e44e02292 Introduce a cc1-level option to provide the path to the module cache, 
where the compiler will look for module files. Eliminates the
egregious hack where we looked into the header search paths for
modules.

Andrew Trick d2e61e1f70 Conditionalize indvars tests that rely on SCEV expansion of geps, 
which is relevant with canonical IVs. Anything else being checked by
these tests is already covered by early CSE.

Eli Friedman 7c5dc122a0 Change a bunch of isVolatile() checks to check for atomic load/store as well. 
No tests; these changes aren't really interesting in the sense that the logic is the same for volatile and atomic.

I believe this completes all of the changes necessary for the optimizer to handle loads and stores correctly.  I'm going to try and come up with some additional testing, though.

Bruno Cardoso Lopes be7a086f58 Not sure how CMPPS and CMPPD had already ever worked, I guess it didn't. 
However with this fix it does now.

Basically the operand order for the x86 target specific node
is not the same as the instruction, but since the intrinsic need that
specific order at the instruction definition, just change the order
during legalization. Also, there were some wrong invertions of condition
codes, such as GE => LE, GT => LT, fix that too. Fix PR10907.

Johnny Chen 3a9838c07b Fix a bug in OptionGroupWatchpoint.cpp where the '-w' option arg parsing result was not checked 
to effect an early error return.

Plus add logic to 'frame variable' command object to check that when watchpoint option is on,
only one variable with exact name (no regex) is specified as the sole command arg.

Argyrios Kyrtzidis 14c32e8894 [libclang] In ASTUnit::Parse copy the CompilerInvocation object instead of 
modifying directly for the preamble.

This avoids an awful, hard to find, bug where "PreprocessorOpts.DisablePCHValidation = true"
would be persistent for subsequent reparses of the translation unit which would result
in defines, present in command-line but not in the PCH, being ignored.

Fixes rdar://9615399.

Jakob Stoklund Olesen eecb2fb183 Add an interface for SplitKit complement spill modes. 
SplitKit always computes a complement live range to cover the places
where the original live range was live, but no explicit region has been
allocated.

Currently, the complement live range is created to be as small as
possible - it never overlaps any of the regions.  This minimizes
register pressure, but if the complement is going to be spilled anyway,
that is not very important.  The spiller will eliminate redundant
spills, and hoist others by making the spill slot live range overlap
some of the regions created by splitting.  Stack slots are cheap.

This patch adds the interface to enable spill modes in SplitKit.  In
spill mode, SplitKit will assume that the complement is going to spill,
so it will allow it to overlap regions in order to avoid back-copies.
By doing some of the spiller's work early, the complement live range
becomes simpler.  In some cases, it can become much simpler because no
extra PHI-defs are required.  This will speed up both splitting and
spilling.

This is only the interface to enable spill modes, no implementation yet.
