e542e3e2ad fix the encoding of sldt GR16 to have the 0x66 prefix, and 
add sldt GR32, which isn't documented in the intel manual

c48bd41698 add various broken forms of fnstsw. I didn't add the %rax 
version because it adds a prefix and makes even less sense
than the other broken forms.  This wraps up rdar://8431422

901a646188 Reapply r113875 with additional cleanups. 
"The register specified for a dregpair is the corresponding Q register, so to
get the pair, we need to look up the sub-regs based on the qreg. Create a
lookup function since we don't have access to TargetRegisterInfo here to
be able to use getSubReg(ARM::dsub_[01])."

Additionaly, fix the NEON VLD1* and VST1* instruction patterns not to use
the dregpair modifier for the 2xdreg versions. Explicitly specifying the two
registers as operands is more correct and more consistent with the other
instruction patterns. This enables further cleanup of special case code in the
disassembler as a nice side-effect.

ebbc4df924 Remove the experimental AliasAnalysis::getDependency interface, which 
isn't a good level of abstraction for memdep. Instead, generalize
AliasAnalysis::alias and related interfaces with a new Location
class for describing a memory location. For now, this is the same
Pointer and Size as before, plus an additional field for a TBAA tag.

Also, introduce a fixed MD_tbaa metadata tag kind.

1a69820d6d Make NEON ld/st pseudo instruction classes take the instruction itinerary as 
an argument, so that we can distinguish instructions with the same register
classes but different numbers of registers (e.g., vld3 and vld4).  Fix some
of the non-pseudo NEON ld/st instruction itineraries to reflect the number
of registers loaded or stored, not just the opcode name.

357e2fe748 Eliminate a 'tst' that immediately follows an 'and' 
by morphing the 'and' to its recording form 'andS'.

This is basically a test commit into this area, to
see whether the bots like me. Several generalizations
can be applied and various avenues of code simplification
are open. I'll introduce those as I go.

I am aware of stylistic input from Bill Wendling, about
where put the analysis complexity, but I am positive
that we can move things around easily and will find a
satisfactory solution.

2a6b987773 When a function-local value with function-local metadata uses gets RAUWed with a 
non-function-local value, it may result in the metadata no longer needing to be
function-local. Check for this condition, and clear the isFunctionLocal flag, if
it's still in the uniquing map, since any node in the uniquing map needs to have
an accurate function-local flag.

Also, add an assert to help catch problematic cases.
