6fde0bd39b 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.

897dd0c588 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]

9ab0427015 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.

2ad4aca8b2 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.

c6e704df8d 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.

0a3dc10eba Add N2RegVShLFrm and N2RegVShRFrm formats so that the disassembler can easily 
dispatch to the appropriate routines to handle the different interpretations of
the shift amount encoded in the imm6 field.  The Vd, Vm fields are interpreted
the same between the two, though.

See, for example, A8.6.367 VQSHL, VQSHLU (immediate) for N2RegVShLFrm format and
A8.6.368 VQSHRN, VQSHRUN for N2RegVShRFrm format.
