59858cf792 Change the assembly syntax for nsw, nuw, and exact, putting them 
after their associated opcodes rather than before. This makes them
a little easier to read.

30c4a3b9a8 finish simplifying DarwinTargetAsmInfo::SelectSectionForGlobal 
for now.  Make the section switching directives more consistent
by not including \n and including \t for them all.

e3577da6d9 simplify DarwinTargetAsmInfo::SelectSectionForGlobal a bit 
and make it more aggressive, we now put:

const int G2 __attribute__((weak)) = 42;

into the text (readonly) segment like gcc, previously we put
it into the data (readwrite) segment.

6dc82863a6 remove this test. It is currently failing because we now emit the string 
on darwin with ".cstring" instead of ".section  __TEXT,__cstring".  They
are the same and the former is better.  Remove this because this is no longer
magic pixie dust in the frontend.

66ac53165e Change Thumb2 jumptable codegen to one that uses two level jumps: 
Before:
      adr r12, #LJTI3_0_0
      ldr pc, [r12, +r0, lsl #2]
LJTI3_0_0:
      .long    LBB3_24
      .long    LBB3_30
      .long    LBB3_31
      .long    LBB3_32

After:
      adr r12, #LJTI3_0_0
      add pc, r12, +r0, lsl #2
LJTI3_0_0:
      b.w    LBB3_24
      b.w    LBB3_30
      b.w    LBB3_31
      b.w    LBB3_32

This has several advantages.
1. This will make it easier to optimize this to a TBB / TBH instruction +
   (smaller) table.
2. This eliminate the need for ugly asm printer hack to force the address
   into thumb addresses (bit 0 is one).
3. Same codegen for pic and non-pic.
4. This eliminate the need to align the table so constantpool island pass
   won't have to over-estimate the size.

Based on my calculation, the later is probably slightly faster as well since
ldr pc with shifter address is very slow. That is, it should be a win as long
as the HW implementation can do a reasonable job of branch predict the second
branch.

f98d253bc5 Make some existing optimizations that would only trigger on scalars 
also apply to vectors.  This allows us to compile this:

#include <emmintrin.h>
__m128i a(__m128 a, __m128 b) { return a==a & b==b; }
__m128i b(__m128 a, __m128 b) { return a!=a | b!=b; }

to:

_a:
	cmpordps	%xmm1, %xmm0
	ret
_b:
	cmpunordps	%xmm1, %xmm0
	ret

with clang instead of to a ton of horrible code.

5fe2b03779 change a test to run in filecheck style. Rename it to be a general 
dumping ground of various SSE4.1 tests, since filecheck can reasonably
handle them all in one file.  Generalize it to check x86-64 stuff as
well since it has a different ABI (a convenient way to test both the 
reg and mem forms of these instructions).
