Consolidate the individual declarations together for ease of reference. This
mirrors the organization in X86, as well, so is good for consistency. No
functional change.

of calling getAllMetadata(). This is semantically identical, but doing
it this way avoids unpacking the DebugLoc.

an MDNode. This saves a bunch of time and memory in the IR linker, e.g. when
doing LTO of files with debug info.

ldm/stm are the cannonical spellings for ldmia/stmia, so use them as such.
Update the parsing/encoding tests accordingly.

During type legalization we often use the SIGN_EXTEND_INREG SDNode.
When this SDNode is legalized during the LegalizeVector phase, it is
scalarized because non-simple types are automatically marked to be expanded.
In this patch we add support for lowering SIGN_EXTEND_INREG manually.
This fixes CodeGen/X86/vec_sext.ll when running with the '-promote-elements'
flag.

TargetAsmInfo, which in turn pulls in TargetRegisterInfo, etc. :-( There are
other cases of violations, but this is probably the worst.
This patch is but one small step towards fixing this. 500 more steps to go. :-(

Original commit message:
Count references to interference cache entries.
Each InterferenceCache::Cursor instance references a cache entry. A
non-zero reference count guarantees that the entry won't be reused for a
new register.
This makes it possible to have multiple live cursors examining
interference for different physregs.
The total number of live cursors into a cache must be kept below
InterferenceCache::getMaxCursors().
Code generation should be unaffected by this change, and it doesn't seem
to affect the cache replacement strategy either.

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".
