Avoid unnecessary duplication of operand 0 of X86::FpSET_ST0_80. This duplication would
cause one register to remain on the stack at the function return.

This unifies all the targets supported by an OS into a template.
It also cleans up the differences between the darwin targets.
Also __LP64__ wasn't needed for *BSD, since x86-64 target defines it anyway.

"semantic analysis" part. Use the "semantic analysis" part when
performing template instantiation on a DeclRefExpr, rather than an ad
hoc list of rules to construct DeclRefExprs from the instantiation.
A test case for this change will come in with a large commit, which
illustrates what I was actually trying to work on.

unknown for it.
Mark the super region of a live region as live, if the live region is pointed
to by a live pointer variable.
These fixes xfail_regionstore_wine_crash.c.

The register allocator, when it allocates a register to a virtual register defined by an implicit_def, can allocate any physical register without worrying about overlapping live ranges. It should mark all of operands of the said virtual register so later passes will do the right thing.
This is not the best solution. But it should be a lot less fragile to having the scavenger try to track what is defined by implicit_def.

Remove ASTContext parameter from DeclContext's methods. This change cascaded down to other Decl's methods and changes to call sites started "escalating".
Timings using pre-tokenized "cocoa.h" showed only a ~1% increase in time run between and after this commit.

The implementations of these methods can Use Decl::getASTContext() to get the ASTContext.
This commit touches a lot of files since call sites for these methods are everywhere.
I used pre-tokenized "carbon.h" and "cocoa.h" headers to do some timings, and there was no real time difference between before the commit and after it.

This is simple enough, but then I thought it would be nice to make PrintingPolicy
get a LangOptions so that various things can key off "bool" and "C++" independently.
This spiraled out of control. There are many fixme's, but I think things are slightly
better than they were before.
One thing that can be improved: CFG should probably have an ASTContext pointer in it,
which would simplify its clients.

- Don't print "Parsing" in front of every message.
- Take additional "type" argument which is prepended to the message (with ": ")
if given.
- Update clients to print errors (warnings) as:
<filename>:<line number>: error(warning): ...
