Add instalias for default 'sy' option. Add tests.

The cache entry referenced by the best split candidate could become
clobbered by an unsuccessful candidate.

The correct fix here is to use reference counts on the cache entries.
Coming up.

Flesh out the options supported for the instruction. Shuffle tests a bit and
add entries for the rest of the options. Add an alias to handle the default
operand of "sy".

Add a target-indepedent entry to MCInstrDesc to describe the encoded size of an opcode.  Switch ARM over to using that rather than its own special MCInstrDesc bits.

llvm-svn: 135106

The frameless unwind stack has a special encoding, the algorithm for which is in
"permuteEncode".

llvm-svn: 135103

Add range checking and testing for parsing and encoding of DBG instruction.

Rename struct Init to class Init for consistency and in preparation
for making Init a FoldingSetNode.

it's later selected to a ANDNPD/ANDNPS instruction instead of the PANDN
instruction. Rename it.

Combine redundant base classes and such. No indended functional change.

Make sure we don't combine a large displacement and a frame index in the same addressing mode on x86-64.  It can overflow, leading to a crash/miscompile.

They're all Thumb2 only, not just some of them. More refactoring cleanup
coming.

llvm-svn: 135081

Some pysical registers create split solutions that would spill anywhere.
They should not even be considered in future multi-way global splits.

This does not affect code generation (yet).

llvm-svn: 135080

Refactor out checking for displacements on x86-64 addressing modes.  No functionality change.  Refactoring in preparation for an additional safety check in FoldOffsetIntoAddress.
