f0a1acba8c Proper encoding for VLDM and VSTM instructions. The register lists for these 
instructions have to distinguish between lists of single- and double-precision
registers in order for the ASM matcher to do a proper job. In all other
respects, a list of single- or double-precision registers are the same as a list
of GPR registers.

d144bb1ddc Covert VORRIMM to be produced via early target-specific DAG combining, rather than legalization. 
This is both the conceptually correct place for it, as well as allowing it to be more aggressive.

1a89511e5d Add support for code generation of the one register with immediate form of vorr. 
We could be more aggressive about making this work for a larger range of constants,
but this seems like a good start.

98f9965c89 Unlike a lot of NEON instructions, vext isn't _actually_ parameterized by element size. Instead, 
all of the different element sizes are pseudo instructions that map down to vext.8 underneath, with
the immediate shifted left to reflect the increased element size.

34599f4aa8 The MC code couldn't handle ARM LDR instructions with negative offsets: 
vldr.64 d1, [r0, #-32]

The problem was with how the addressing mode 5 encodes the offsets. This change
makes sure that the way offsets are handled in addressing mode 5 is consistent
throughout the MC code. It involves re-refactoring the "getAddrModeImmOpValue"
method into an "Imm12" and "addressing mode 5" version. But not to worry! The
majority of the duplicated code has been unified.

Bill Wendling
1546322a9c Rename getAddrModeImm12OpValue to getAddrModeImmOpValue and expand it to work 
with immediates up to 16-bits in size. The same logic is applied to other LDR
encodings, e.g. VLDR, but which use a different immediate bit width (8-bits in
VLDR's case). Removing the "12" allows it to be more generic.

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.
