SROA: Use CRTP for OpSplitter to get rid of virtual dispatch and the virtual-dtor warnings that come with it.

SROA: Replace the member function template contraption for recursively splitting aggregates into a real class.

No intended functionality change.

store this and use it to not emit long nops when the CPU is geode which
doesnt support them.

Fixes PR11212.

This makes Clang warn about self references in in-class initializers,
for example:

  struct S {
    int a = a + 42;
  };

This basically just moves UninitializedFieldVisitor up a bit in
SemaDeclCXX.cpp, and adds a call to it from ActOnCXXInClassMemberInitializer.

...I don't know why this could appease msvc...baad.

Without this patch, the isDerivedFrom matcher asserts in the
"assert(ClassDecl != NULL);" in the new test, as a
DependentTemplateSpecilizationType is not a sub-type of
TemplateSpecializationType and also does not offer getAsCXXRecordDecl().

I am not sure why this did not cause problems before. It is now (after
the changed implementation of isDerivedFrom) easier to write a matcher
that actually gets into this branch of the code.

Having Expr-subclass-matchers being VariadicDynCast-Expr-matchers does
not provide additional type safety and just makes using them harder. In
the clang AST, expressions are always statements and an expression
matcher can be used anywhere, a statement matcher is expected. Any given
matcher definition still has at least one noun.

a fix to getCommonType in the previous patch.

FCAs. This is essential in order to promote allocas that are used in
struct returns by frontends like Clang. The FCA load would block the
rest of the pass from firing, resulting is significant regressions with
the bullet benchmark in the nightly test suite.

Thanks to Duncan for repeated discussions about how best to do this, and
to both him and Benjamin for review.

This appears to have blocked many places where the pass tries to fire,
and so I'm expect somewhat different results with this fix added.

As with the last big patch, I'm including a change to enable the SROA by
default *temporarily*. Ben is going to remove this as soon as the LNT
bots pick up the patch. I'm just trying to get a round of LNT numbers
from the stable machines in the lab.

NOTE: Four clang tests are expected to fail in the brief window where
this is enabled. Sorry for the noise!

[TSan] s/uintptr_t/intptr_t in TSan test and enforce stack size limit in one of TSan output tests that somewhy fails otherwise

More domain conversion; convert VFP VMOVS to NEON instructions in more cases - when we may clobber the other S-lane by converting an S to a D instruction, make an effort to work out if the S lane is clobberable or not.

[Sanitizer] llvm-symbolizer: turn off symbol table lookup by default while getSymbolAddress from libObject returns wrong values

[ASan] Move printing descriptions of heap addresses in error report from allocator internals to asan_report.cc.

[TSan] port all output tests to lit and move them to lit_tests directory. This makes 'make check-tsan' command test both unit and output TSan tests. Old custom makefiles for running TSan tests are still functional as well.

Make custom operand parsing mnemonic indices use the same mnemonic table as the match table. Reorder fields in OperandMatchEntry to provide the least amount of padding for in tree targets.

llvm-svn: 164109

Use variable type for index into mnemonic table. Shrinks size of index field on in tree targets. Saving static data space.

Now where we used to call ReInitMCSubtargetInfo, we actually recompute
the same information as InitMCSubtargetInfo instead of only setting
the feature bits.
