ca7ae418a5 Check register class matching instead of width of type matching
when determining validity of matching constraint. Allow i1
types access to the GR8 reg class for x86.

Fixes PR10352 and rdar://9777108

e18641e454 Reorganize ARM assembler aliases.
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.

c7d5a58efc manually copy debugloc over to a new instruction in clone() instead
of calling getAllMetadata().  This is semantically identical, but doing
it this way avoids unpacking the DebugLoc.

f9d3b2a8c3 Stop the ValueMapper from calling getAllMetadata, which unpacks DebugLoc into
an MDNode.  This saves a bunch of time and memory in the IR linker, e.g. when 
doing LTO of files with debug info.

b93249b1e7 [VECTOR-SELECT]
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.

3d2be55d6c Unfortunately several files in MC are badly violating layering rule by using
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. :-(

b0af7bda8d Reapply r135121 with a fixed copy constructor.
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.
