Jim Grosbach 9398141c48 ARM assembly parsing and encoding for LDC{2}{L}/STC{2}{L} instructions.
Fill out the rest of the encoding information, update to properly mark
the LDC/STC instructions as predicable while the LDC2/STC2 instructions are
not, and adjust the parser accordingly.

Nick Lewycky 3e01bd3b60 Apparently, sometimes llvm-nm doesn't put the undefined symbol at the top. Take
that into account and test for no U's showing up in the middle, which is what
we really wanted to test for.

Nick Lewycky 29e7b315ac Also create a shndx even if there are no symbols. This lets us test
.symtab_shndx reading and writing together, and finally we have a testcase for
r141440.

Jakob Stoklund Olesen b253f490c3 Insert dummy ED table entries for pseudo-instructions.
The table is indexed by opcode, so simply removing pseudo-instructions
creates a wrong mapping from opcode to table entry.

Add a test case for xorps which has a very high opcode that exposes this
problem.

Craig Topper 5aebebe18d Revert part of r141274. Only need to change encoding for xchg %eax, %eax in 64-bit mode. This is because in 64-bit mode xchg %eax, %eax implies zeroing the upper 32-bits of RAX which makes it not a NOP. In 32-bit mode using NOP encoding is fine.

Craig Topper 88cb33e0d4 Fix disassembler handling of CRC32 which is an odd instruction that uses 0xf2 as an opcode extension and allows the opsize prefix. This necessitated adding IC_XD_OPSIZE and IC_64BIT_XD_OPSIZE contexts. Unfortunately, this increases the size of the disassembler tables. Fixes PR10702.

James Molloy 21efa7d6e1 Check in a patch that has already been code reviewed by Owen that I'd forgotten to commit.
Build on previous patches to successfully distinguish between an M-series and A/R-series MSR and MRS instruction. These take different mask names and have a *slightly* different opcode format.

Add decoder and disassembler tests.

Improvement on the previous patch - successfully distinguish between valid v6m and v7m masks (one is a subset of the other). The patch had to be edited slightly to apply to ToT.
