In functions that only need to use the CGCXXABI member of a CodeGenTypes
class, pass that reference around directly rather than a reference to
a CodeGenTypes class.

This makes the actual dependence on CGCXXABI clear at the call sites.

The most likely case where this error happens is when the user specifies
too many register operands. Don't make it look like an internal LLVM bug
when we can see that the error is coming from an inline asm instruction.
For other instructions we keep the "ran out of registers" error.

Use logical/arithmetic operations instead of builtins in tbmintrin.h. This way we can remove the intrinsic support from the backend.

When MC was first added, targets could use hasRawTextSupport to keep features
working before they were added to the MC interface.

The design goal of MC is to provide an uniform api for printing assembly and
object files. Short of relaxations and other corner cases, a object file is
just another representation of the assembly.

It was never the intention that targets would keep doing things like

if (hasRawTextSupport())
  Set flags in one way.
else
  Set flags in another way.

When they do that they create two code paths and the object file is no longer
just another representation of the assembly. This also then requires testing
with llc -filetype=obj, which is extremelly brittle.

This patch removes some of these hacks by replacing them with smaller ones.
The ARM flag setting is trivial, so I just moved it to the constructor. For
Mips, the patch adds two temporary hack directives that allow the assembly
to represent the same things as the object file was already able to.

The hope is that the mips developers will replace the hack directives with
the same ones that gas uses and drop the -print-hack-directives flag.

I will also try to implement a target streamer interface, so that we can
move this out of the common code.

In summary, for any new work, two rules of the thumb are
  * Don't use "llc -filetype=obj" in tests.
  * Don't add calls to hasRawTextSupport.

The command-line for clang-apply-replacements was being mangled due to an
uninitialized variable. gasp! Now fixed.

llvm-svn: 192033

Summary:
The clang-apply-replacements process is now invoked to apply
replacements between applying transforms. This resulted in a massive
simplification of the tool:
- FileOverrides class no longer needed.
- Change tracking and code formatting no longer needed.
- No more dependency on libclangApplyReplacements.
- Final syntax check is easier to do directly now than with a separate
  header/source pair.

Replacement handling stuff abstracted into a new header/source pair to
de-clutter ClangModernize.cpp somewhat.

Tests updated.

Add OPC_CheckChildSame0-3 to the DAG isel matcher. This replaces sequences of MoveChild, CheckSame, MoveParent. Saves 846 bytes from the X86 DAG isel matcher, ~300 from ARM, ~840 from Hexagon.

DW_TAG_pointer_type is updated to use DITypeRef.

Paired commit with r192018.

llvm-svn: 192019

is updated to use DITypeRef.

Move isUnsignedDIType and getOriginalTypeSize from DebugInfo.h to be static
helper functions in DwarfCompileUnit. We already have a static helper function
"isTypeSigned" in DwarfCompileUnit, and a pointer to DwarfDebug is added to
resolve the derived-from field. All three functions need to go across link
for derived-from fields, so we need to get hold of a type identifier map.

A pointer to DwarfDebug is also added to DbgVariable in order to resolve the
derived-from field.

Debug info verifier is updated to check a derived-from field is a TypeRef.
Verifier will not go across link for derived-from fields, in debug info finder,
we go across the link to add derived-from fields to types.

Function getDICompositeType is only used by dragonegg and since dragonegg does
not generate identifier for types, we use an empty map to resolve the
derived-from field.

When printing a derived-from field, we use DITypeRef::getName to either return
the type identifier or getName of the DIType.

A paired commit at clang is required due to changes to DIBuilder.
