virtual base registers handle this function, and more. A bit more cleanup
to do on the interface to eliminateFrameIndex() after this.

Fix horrible GRExprEngine bug where switch statements with no 'case:' statements would cause the path to get prematurely aborted.  Fixes <rdar://problem/8360854>.

is a vector to be a vector element extraction.  This allows clang to
compile:

struct S { float A, B, C, D; };
float foo(struct S A) { return A.A + A.B+A.C+A.D; }

into:

_foo:                                   ## @foo
## BB#0:                                ## %entry
	movd	%xmm0, %rax
	shrq	$32, %rax
	movd	%eax, %xmm2
	addss	%xmm0, %xmm2
	movapd	%xmm1, %xmm3
	addss	%xmm2, %xmm3
	movd	%xmm1, %rax
	shrq	$32, %rax
	movd	%eax, %xmm0
	addss	%xmm3, %xmm0
	ret

instead of:

_foo:                                   ## @foo
## BB#0:                                ## %entry
	movd	%xmm0, %rax
	movd	%eax, %xmm0
	shrq	$32, %rax
	movd	%eax, %xmm2
	addss	%xmm0, %xmm2
	movd	%xmm1, %rax
	movd	%eax, %xmm1
	addss	%xmm2, %xmm1
	shrq	$32, %rax
	movd	%eax, %xmm0
	addss	%xmm1, %xmm0
	ret

... eliminating half of the horribleness.

Change "Current" as in GetCurrentThread, GetCurrentStackFrame, etc, to "Selected" i.e. GetSelectedThread.  Selected makes more sense, since these are set by some user action (a selection).  I didn't change "CurrentProcess" since this is always controlled by the target, and a given target can only have one process, so it really can't be selected.

still having a significant effect. It shouldn't be now that the pre-RA
virtual base reg stuff is in. Assuming that's valididated by the nightly
testers, we can simplify a lot of the PEI frame index code.

  with the only exception of launching the process from SBTarget which is under
  investigation.

o build-swig-Python.sh should also checks the timestamp of ${swig_input_file}
  for update eligibility.  Also, once an update is in order, there's no need
  to check the remaining header files for timestamps.

o Coaches swig to treat StopReason as an int type, instead of a C++ class.
