Silviu Baranga ddc67a7655 Added the missing bit definition for the 4th bit of the STR (post reg) instruction. It is now set to 0. The patch also sets the unpredictable mask for SEL and SXTB-type instructions.

Jim Grosbach 2937df45a8 ARM: Update NEON assembly two-operand aliases. 
Use the new TwoOperandAliasConstraint to handle lots of the two-operand aliases
for NEON instructions. There's still more to go, but this is a good chunk of
them.

Jim Grosbach d28ef9ac46 Simplify some NEON assembly pseudo definitions. 
Let the generic token alias definitions handle the data subtype
suffices. We don't need explicit versions for each.

Jim Grosbach f0d25117c6 ARM VFP add encoding of the bitcount to fixed-point<-->floating point. insns. 
The value from the operands isn't right yet, but we weren't encoding it at
all previously. The parser needs to twiddle the values when building the
instruction.

Jim Grosbach 3e941aee69 ARM thumb assembly parsing for arithmetic flag setting instructions. 
Thumb one requires that many arithmetic instruction forms have an 'S'
suffix. For Thumb2, the whether the suffix is required or precluded depends
on whether the instruction is in an IT block. Use target parser predicates
to check for these sorts of context-sensitive constraints.

Owen Anderson e0152a73c2 Replace the existing ARM disassembler with a new one based on the FixedLenDecoderEmitter. 
This new disassembler can correctly decode all the testcases that the old one did, though
some "expected failure" testcases are XFAIL'd for now because it is not (yet) as strict in
operand checking as the old one was.

Jim Grosbach d359571120 ARM refactoring assembly parsing of memory address operands. 
Memory operand parsing is a bit haphazzard at the moment, in no small part
due to the even more haphazzard representations of memory operands in the .td
files. Start cleaning that all up, at least a bit.

The addressing modes in the .td files will be being simplified to not be
so monolithic, especially with regards to immediate vs. register offsets
and post-indexed addressing. addrmode3 is on its way with this patch, for
example.

This patch is foundational to enable going back to smaller incremental patches
for the individual memory referencing instructions themselves. It does just
enough to get the basics in place and handle the "make check" regression tests
we already have.

Follow-up work will be fleshing out the details and adding more robust test
cases for the individual instructions, starting with ARM mode and moving from
there into Thumb and Thumb2.
