Initial step -- infrastructure change -- to fix the bug.  Change the RegisterInfo data structure
to contain two additional fields (uint32_t *value_rges and uint32_t *invalidate_regs) to facilitate
architectures which have register mapping.

Update all existing RegsiterInfo arrays to have two extra NULL's (the additional fields) in each row,
GDBRemoteRegisterContext.cpp is modified to add d0-d15 and q0-q15 register info entries which take
advantage of the value_regs field to specify the containment relationship:

d0 -> (s0, s1)
...
d15 -> (s30, s31)
q0 -> (d0, d1)
...
q15 -> (d30, d31)

Extract a base class and provide four specific sub-classes for iterating
over const/non-const bundles/instructions.

This eliminates the mystery bool constructor argument.

 - This fixes make_absolute to not basically always call current_path() on
   Unix systems.
 - I think the API probably needs cleanup in this area, but I'll let Michael
   handle that.

Without this hook, functions w/ a completely empty body (including no
epilogue) will cause an MCEmitter assertion failure.

For example,
define internal fastcc void @empty_function() {
  unreachable
}

SlotIndexes are not assigned to instructions inside bundles, but it is
still valid to look up the index of those instructions.

The reverse getInstructionFromIndex() will return the first instruction
in the bundle.

In the ObjectFile interface, replace isInternal(), isAbsolute(), isGlobal(), and isWeak(), with a bitset of flags.

Original log:
---------------------
Correctly track tags and enum members defined in the prototype of a function, and ensure they are properly scoped.

This fixes code such as:

enum e {x, y};
int f(enum {y, x} n) {
 return 0;
}

This finally fixes PR5464 and PR5477.
---------------------

I also reverted r151641 which was enhancement on top of r151638.

[analyzer diagnostics] Refactor filtration for PathDiagnosticConsumers that don't support cross-file diagnostics
into a common place.  Currently enable this filtration for Plist diagnostics as well.

llvm-svn: 151664

[analyzer diagnostics] start prototyping stripping PathDiagnostics of unnecessary cruft caused by path inlining.

This introduces a concept of a "prunable" PathDiagnosticEvent.  Currently this is a flag, but
we may evolve the concept to make this more dynamically inferred.

ELF linkers don't know dwarf, so they depend on these relocations to produce

Un-break clang based on r151638 - What was meant to be a trivial variable name change went horribly wrong and I forgot to retest afterwards.
