3f060e3216 add an optimized form of OPC_EmitMergeInputChains for the 1, 0 and
1, 1 cases which are by-far the most frequent.  This shrinks the X86
isel table from 77014 -> 74657 bytes.

727548a580 Oops, r98447 dropped the reference to ForwardType in the wrong place in
Type::destroy(), so it got skipped for FunctionTypes, StructTypes, and
UnionTypes.  This fixes the resulting leaks in test/Feature/opaquetypes.ll and
test/Integer/opaquetypes_bt.ll.

70189ff5ab fix a long standing fixme, which required fixing a bunch of other
issues to get here.  We now trim the result type list of the
CompleteMatch or MorphNodeTo operation to be the same size as the
thing we're matching.  this means that if you match (add GPR, GPR)
with an instruction that produces a normal result and a flag that
we now trim the result in tblgen instead of having to do it 
dynamically.  This exposed a bunch of inconsistencies in result
counting that happened to be getting lucky since the days of the
old isel.

d6afc9e48d fix CodeGenTarget::getRegisterVTs to not return the
same vt multiple times for a register.  For example,
ECX is in 5 different i32 reg classes, just return 
1 i32 instead of 5.

from two places in CodeGenDAGPatterns.cpp, and

ad983d7a8a continue pushing tblgen's support for nodes with multiple

produces one implicit def and one result instead of one or
the other when not at the root of the pattern.

cf18deaea3 When we promote a load of an argument make sure to take the alignment
of the previous load - it's usually important.  For example, we don't want
to blindly turn an unaligned load into an aligned one.

794a9a3941 Add NVMulSLFrm to represent "3-register multiply with scalar" operations and set
it as the format for the appropriate N3V*SL*<> classes.  These instructions
require special handling of the M:Vm field which encodes the restricted Dm and
the lane index within Dm.

Examples are A8.6.325 VMLA, VMLAL, VMLS, VMLSL (by scalar):

	vmlal.s32	q3, d2, d10[0]

f884dba43d Thumb2 storeFrom/LoadToStackSlot() need to handle tGPR regs directly, not pass
through to the generic version. The generic functions use STR/LDR, but T2
needs the t2STR/t2LDR instead so we get the addressing mode correct.

dc6507730a If we mark clean-ups as clean-ups, then it could break when inlining through an
'invoke' instruction. You will get a situation like this:

bb:
  %ehptr = eh.exception()
  %sel = eh.selector(%ehptr, @per, 0);

...

bb2:
  invoke _Unwind_Resume_or_Rethrow(%ehptr) %normal unwind to %lpad

lpad:
  ...

The unwinder will see the %sel call as a clean-up and, if it doesn't have a
catch further up the call stack, it will skip running it. But there *is* another
catch up the stack -- the catch for the %lpad. However, we can't see that. This
is fixed in code-gen, where we detect this situation, and convert the "clean-up"
selector call into a "catch-all" selector call. This gives us the correct
semantics.

4a97a176e7 Add N3RegVShFrm to represent 3-Register Vector Shift Instructions, which do not
follow the N3RegFrm's operand order of D:Vd N:Vn M:Vm.  The operand order of
N3RegVShFrm is D:Vd M:Vm N:Vn (notice that M:Vm is the first src operand).

Add a parent class N3Vf which requires passing a Format argument and which the
N3V class is modified to inherit from.  N3V class represents the "normal"
3-Register NEON Instructions with N3RegFrm.

Also add a multiclass N3VSh_QHSD to represent clusters of NEON 3-Register Shift
Instructions and replace 8 invocations with it.
