Jim Ingham 2561aa6124 Change the "-S", "-F" and "-M" options to take their arguments directly, rather than requiring the -n option. This means you can't "or" together the types (i.e. set a breakpoint on a method or selector called "whatever". But that is a pretty uncommon operation, and having to provide two flags for the more common "set a breakpoint on this selector" is annoying.

Jim Grosbach 2a1915d04b Remove the now obsolete frame index virtual re-use algorithm from PEI. Pre-RA 
virtual base registers handle this function, and more. A bit more cleanup
to do on the interface to eliminateFrameIndex() after this.

Chris Lattner bfd2228182 optimize "integer extraction out of the middle of a vector" as produced 
by SRoA.  This is part of rdar://7892780, but needs another xform to

Chris Lattner d4ebd6df5a optimize bitcast(trunc(bitcast(x))) where the result is a float and 'x' 
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.

Jim Ingham 2976d00adb 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.

Jim Grosbach 17da935964 Turn off the scavenging based frame reg reuse briefly to measure whether it's 
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.

Chris Lattner d774ae9ed1 fix 2xi16 to pass as i32 instead of <2 x i16>. The former passes in 
memory (as required) the later now passes in an xmm register.  This
fixes gcc.dg/compat/vector_1 on x86-32.

Johnny Chen 5fca8ca8cd o Added a test case for array_types which uses the Python APIs from lldb.py, 
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.
