This increases the maximum for MVT::LAST_VALUETYPE

This change doubles the allowable value for MVT::LAST_VALUETYPE. It does
this by doing several things.

1. Introduces MVT::MAX_ALLOWED_LAST_VALUETYPE which in this change has a
value of 64.  This value contains the current maximum for the
MVT::LAST_VALUETYPE.

2. Instead of checking "MVT::LAST_VALUETYPE <= 32", all of those uses
now become "MVT::LAST_VALUETYPE <= MVT::MAX_ALLOWED_LAST_VALUETYPE"

3. Changes the dimension of the ValueTypeActions from 2 elements to four
elements and adds comments ahead of the declaration indicating the it is
"(MVT::MAX_ALLOWED_LAST_VALUETYPE/32) * 2".  This at least lets us find
what is affected if and when MVT::MAX_ALLOWED_LAST_VALUETYPE gets
changed.

4. Adds initializers for the new elements of ValueTypeActions.

This does NOT add any types in MVT. That would be done separately.

This doubles the size of ValueTypeActions from 64 bits to 128 bits and
gives us the freedom to add more types for AVX.

On Darwin, ams printer should output a second label before a jump table so the linker knows it's a new atom. But this is only needed if the jump table is put in a separate section from the function body.

- Update register allocation hint after coalescing. This is done by the target since the hint is target dependent. This is important for ARM register pair hints.
- Register allocator should resolve the second part of the hint (register number) before passing it to the target since it knows virtual register to physical register mapping.
- More fixes to get ARM load / store double word working.

If a val# is defined by an implicit_def and it is being removed, all of the copies off the val# were removed. This causes problem later since the scavenger will see uses of registers without defs. The proper solution is to change the copies into implicit_def's instead.

TurnCopyIntoImpDef turns a copy into implicit_def and remove the val# defined by it. This causes an scavenger assertion later if the def reaches other blocks. Disable the transformation if the value live interval extends beyond its def block.
