44d2802e1d Shifter ops are not always free. Do not fold them (especially to form 
complex load / store addressing mode) when they have higher cost and
when they have more than one use.

cdc8dff3ac SelectionDAG shuffle nodes do not allow operands with different numbers of 
elements than the result vector type.  So, when an instruction like:

%8 = shufflevector <2 x float> %4, <2 x float> %7, <4 x i32> <i32 1, i32 0, i32 3, i32 2>

is translated to a DAG, each operand is changed to a concat_vectors node that appends 2 undef elements.  That is:

shuffle [a,b], [c,d] is changed to:
shuffle [a,b,u,u], [c,d,u,u]

That's probably the right thing for x86 but for NEON, we'd much rather have:

shuffle [a,b,c,d], undef

Teach the DAG combiner how to do that transformation for ARM.  Radar 8597007.

e812b356cc Tweaks to X86 instructions to allow the 'w' suffix in places it makes 
sense, when the instruction takes the 16-bit ax register or m16 memory
location.  These changes to llvm-mc matches what the darwin assembler
allows for these instructions.  Done differently than in r117031 that
caused a valgrind error which was later reverted.

d5235bb45c Added some aliases to the fcomip and fucompi Intel instructions. So that llvm-mc 
will accept versions that the darwin assembler allows.  Forms ending in "pi" and
forms without all the operands.

e38790534e Implement some relaxations for arithmetic instructions. The limitation 
on RIP relative relocations looks artificial, but this is a superset of
what we were able to do before.

64680cd5b8 Change v64 datalayout in SPU. 
The SPU ABI does not mention v64, and all examples
in C suggest v128 are treated similarily to arrays, 
we use array alignment for v64 too. This makes the 
alignment of e.g. [2 x <2 x i32>] behave "intuitively"
and similar to as if the elements were e.g. i32s.

This also makes an "unaligned store" test to be 
aligned, with different (but functionally equivalent)
code generated.

309484bb46 When the "true" and "false" blocks of a diamond if-conversion are the same, 
do not double-count the duplicate instructions by counting once from the
beginning and again from the end.  Keep track of where the duplicates from
the beginning ended and don't go past that point when counting duplicates
at the end.  Radar 8589805.

This change causes one of the MC/ARM/simple-fp-encoding tests to produce
different (better!) code without the vmovne instruction being tested.
I changed the test to produce vmovne and vmoveq instructions but moving
between register files in the opposite direction.  That's not quite the same
but predicated versions of those instructions weren't being tested before,
so at least the test coverage is not any worse, just different.
