The R0 register can now be allocated because instructions

Hal Finkel 573fc28d64 Use the PPC no-r0 class on the TOC LD pseudos
The register parameter in these instructions becomes the base register in an
r+i ld instruction (and, thus, cannot be r0).

This is not yet testable because we don't yet allocate r0 (and even then any
test would be very fragile).

Hal Finkel 3fa362a51a Apply the no-r0 register class to the PPC SELECT_CC_I[4|8] pseudos
Either operand of these pseudo instructions can be transformed into the first
operand of an isel instruction (and this operand cannot be r0).

any test would be very fragile).

Hal Finkel 42a312b261 Apply the no-r0 class to PPC TOC ADDI[S] pseudo instructions
Like the addi/addis instructions themselves, these pseudo instructions also
cannot have r0 as their register parameter (because it will be interpreted as
the value 0).

This is not yet testable because we don't yet allocate r0 (and even when we do,
any regression test would be very fragile because it would depend on the
register allocator heuristics).

Argyrios Kyrtzidis fff55a028b [lib/Headers] Break the module import cycle between _Builtin_intrinsics.sse and _Builtin_intrinsics.sse2
Module "sse" implicitly exports module "sse2".
This is bad because we also have module "sse2" export module "sse" (as intended) so we end up with a cycle
in the module import graph:
1. sse2 -> (also imports) sse
2. sse -> (also imports) sse2

To eliminate the cycle remove 2.; importing module "sse2" will also import module "sse", but just importing
module "sse" will not also import module "sse2".

Bill Schmidt a1b72d0f6a Remove the link register from the GPR classes on PowerPC.
Some implementation detail in the forgotten past required the link
register to be placed in the GPRC and G8RC register classes.  This is
just wrong on the face of it, and causes several extra intersection
register classes to be generated.  I found this was having evil
effects on instruction scheduling, by causing the wrong register class
to be consulted for register pressure decisions.

No code generation changes are expected, other than some minor changes
in instruction order.  Seven tests in the test bucket required minor
tweaks to adjust to the new normal.

Argyrios Kyrtzidis 3a9c42c423 [modules] Before marking the module imported macros as ambiguous, check if this is a case where
the system macro uses a not identical definition compared to a macro from the clang headers.

For example (these come from different modules):
   \#define LONG_MAX __LONG_MAX__ (clang's limits.h)
   \#define LONG_MAX 0x7fffffffffffffffL (system's limits.h)
in which case don't mark them ambiguous to avoid the "ambiguous macro expansion" warning.

Argyrios Kyrtzidis 09796b9a23 [modules] Re-enable the "ambiguous expansion of macro" warning.
Also update "test/Modules/macros.c" to test modified semantics:
-When there is an ambiguous macro, expand using the latest introduced version, not the first one.
-#undefs in submodules cause the macro to not be exported by that submodule, it doesn't cause
 undefining of macros in the translation unit that imported that submodule.
 This reduces macro namespace interference across modules.

Michael Gottesman 46ebe53ead Added back in the test for arc-annotations.
The test was removed since I had not turned off the test during release

compiled out during release builds. I added the proper requires header
to assuage this issue.

David Blaikie a26d70358f Adding DIImportedModules to DIScopes.
This is just the basic groundwork for supporting DW_TAG_imported_module but I
wanted to commit this before pushing support further into Clang or LLVM so that
this rather churny change is isolated from the rest of the work. The major
churn here is obviously adding another field (within the common DIScope prefix)
to all DIScopes (files, classes, namespaces, lexical scopes, etc). This should
be the last big churny change needed for DW_TAG_imported_module/using directive
support/PR14606.

Ted Kremenek 65d635775d Split "incomplete implementation" warnings for ObjC into separate warnings.
Previously all unimplemented methods for a class were grouped under
a single warning, with all the unimplemented methods mentioned
as notes.  Based on feedback from users, most users would like
a separate warning for each method, with a note pointing back to
the original method declaration.

Hal Finkel a7b0630ba8 Don't spill PPC VRSAVE on non-Darwin (even in SjLj)
As Bill Schmidt pointed out to me, only on Darwin do we need to spill/restore
VRSAVE in the SjLj code. For non-Darwin, don't spill/restore VRSAVE (and I've
added some asserts to make sure that we're not).

As it turns out, we're not currently handling the Darwin case correctly (I've
added a FIXME in the test case). I've tried adding various implied register
definitions/uses to force the spill without success, so I'll need to address
this later.

Douglas Gregor 45bb4834e9 <rdar://problem/13267210> Ensure that Sema::CompareReferenceRelationship returns consistent results with invalid types.
When Sema::RequireCompleteType() is given a class template
specialization type that then fails to instantiate, it returns
'true'. On subsequent invocations, it can return false. Make sure that
this difference doesn't change the result of
Sema::CompareReferenceRelationship, which is expected to remain stable
while we're checking an initialization sequence.

Bill Wendling 5aa82397e8 Use the full path when outputting the `.gcda' file.
If we compile a single source program, the `.gcda' file will be generated where
the program was executed. This isn't desirable, because that place may be at an
unpredictable place (the program could call `chdir' for instance).

Instead, we will output the `.gcda' file in the same place we output the `.gcno'
file. I.e., the directory where the executable was generated. This matches GCC's
behavior.
