Update testcase to be more careful about checking register
values. While regexes are general goodness for these sorts of
testcases, in this example, the registers are constrained by
the calling convention, so we can and should check their
explicit values.

Adding a new data structure for storing the Replacements generated for a single
translation unit. Structure contains a vector of Replacements as well a field
indicating the main source file of the translation unit. An optional 'Context'
field allows for tools to provide any information they want about the context
the Replacements were generated in. This context is printed, for example, when
detecting conflicts during Replacement deduplication.

YAML serialization for this data structure is implemented in this patch. Tests
are included.

This moves the logic for handling -mfoo -mno-foo from the driver to -cc1. It
also changes -cc1 to apply the options in order, fixing pr16943.

The handling of -mno-mmx -msse is now an explicit special case.

The driver validates its options, so we don't need to redo the work in
"clang -cc1".

Updated status of issues #1214, 2207 and 2209. They were already implemented, so no functionality change was needed.

llvm::sys::path::native(dst, dst) might be overridden-safe in most cases, though.

This removes the very long chains of
Feature["avx"] = Feature["sse42"] = ... = true;

This time I managed to forget the test.

It makes no sense to try and compile for arm7tdmi when we're targeting
something like gnueabihf. Although not strictly the most basic hardware
conceivable, I believe arm1176jzf-s is a reasonable compromise (that can always
be overridden explicitly if needed) since it's still in reasonably common use
unlike earlier cores.

Patch by Joe Hermaszewski. Thank you!

This patch adds four new options to control:
- Spaces after control keyworks (if(..) vs if (..))
- Spaces in empty parentheses (f( ) vs f())
- Spaces in c-style casts (( int )1.0 vs (int)1.0)
- Spaces in other parentheses (f(a) vs f( a ))

Patch by Joe Hermaszewski. Thank you for working on this!

The IncludeDirectives class helps with detecting and modifying #include
directives. For now it allows the users to add angled-includes in a source file.
This is a start for this class that will evolve in the future to add more
functionality.

This should fix the reverted commit r188610 (buildbot failures on Windows).

clang/test/Driver/cl-options.c: Remove the feature "clang-driver". It has been working since r188331.

clang/test/Driver: Remove the feature "clang-driver" since gcc-as has not been used with -integrated-as since r177360.

clang/test/Driver: Remove the feature "clang-driver" in three tests since they might work as expected since their first commit.

These instructions were present in a draft spec but were removed before
publication.

We now use MVST, CLST and SRST for the obvious cases.

llvm-svn: 188781

SystemZTargetLowering::emitStringWrapper() previously loaded the character
into R0 before the loop and made R0 live on entry.  I'd forgotten that
allocatable registers weren't allowed to be live across blocks at this stage,
and it confused LiveVariables enough to cause a miscompilation of f3 in
memchr-02.ll.

This patch instead loads R0 in the loop and leaves LICM to hoist it
after RA.  This is actually what I'd tried originally, but I went for
the manual optimisation after noticing that R0 often wasn't being hoisted.
This bug forced me to go back and look at why, now fixed as r188774.

We should also try to optimize null checks so that they test the CC result
of the SRST directly.  The select between null and the SRST GPR result could
then usually be deleted as dead.
