Add code to emulate STRH (Register) Arm instruction.

Remove inaccurate comments from EmulateInstruction::Context definition.

Fix contexts in a few arm instruction emulation routines.

rather than an int. Thankfully, this only causes LLVM to miss optimizations, not
generate incorrect code.

This just fixes the zext at the return. We still insert an i32 ZextAssert when
reading a function's arguments, but it is followed by a truncate and another i8
ZextAssert so it is not optimized.

Having FileManager::getFile always open the file, brought much consternation and leaking of file descriptors.

Add 'openFile' bool to FileManager::getFile to specify whether we want to have the file opened or not, have it
false by default, and enable it only in HeaderSearch.cpp where the open+fstat optimization matters.

overload, so that we actually do the resolution for full expressions
and emit more consistent, useful diagnostics. Also fixes an IRGen
crasher, where Sema wouldn't diagnose a resolvable bound member
function template-id used in a full-expression (<rdar://problem/9108698>).

clients to observe the exact path through which an #included file was
located. This is very useful when trying to record and replay inclusion
operations without it beind influenced by the aggressive caching done
inside the FileManager to avoid redundant system calls and filesystem
operations.

The work to compute and return this is only done in the presence of
callbacks, so it should have no effect on normal compilation.

ActOnFinishFunctionBody/ActOnBlockStmtExpr. This way, we ensure that
we diagnose undefined labels before the jump-scope checker gets run,
since the jump-scope checker requires (as its invariant) that all of
the GotoStmts be wired up correctly.

forward-looking "goto" statement, make sure to insert it *after* the
last declaration in the identifier resolver's declaration chain that
is either outside of the function/block/method's scope or that is
declared in that function/block/method's specific scope. Previously,
we could end up inserting the label ahead of declarations in inner
scopes, confusing C++ name lookup.

Fixes PR9491/<rdar://problem/9140426> and <rdar://problem/9135994>.

Note that the crash-on-invalid PR9495 is *not* fixed. That's a
separate issue.
