Allow direct value types to be used in instruction 'set' patterns.
This makes it possible to define instruction patterns like this:
def LDri : F3_2<3,

(outs IntRegs:$dst), (ins MEMri:$addr),
"ld [$addr], $dst",
[(set i32:$dst, (load ADDRri:$addr))]>;

PPC ZERO register needs a register number of 0.
In order for the new ZERO register to be used with MC, etc. we need to specify
its register number (0).

Note in PPCFunctionInfo VRSAVE spills
In preparation for using the new register scavenger capability for providing
more than one register simultaneously, specifically note functions that have
spilled VRSAVE (currently, this can happen only in functions that use the
setjmp intrinsic). As with CR spilling, such functions will need to provide two
emergency spill slots to the scavenger.

Use direct types in Sparc def : Pat patterns.
The SelectionDAG graph has MVT type labels, not register classes, so
this makes it clearer what is happening.
This notation is also robust against adding more types to the IntRegs

Allow direct value types in pattern definitions.
Just like register classes, value types can be used in two ways in
patterns:
(sext_inreg i32:$src, i16)
In a named leaf node like i32:$src, the value type simply provides the
type of the node directly. This simplifies type inference a lot compared
to the current practice of specifiying types indirectly with register
classes.
As an unnamed leaf node, like i16 above, the value type represents
itself as an MVT::Other immediate.

Cleanup some unused reg. scavenger parameters in PPCRegisterInfo
These spilling functions will eventually make use of the register scavenger,
however, they'll do so by taking advantage of PEI's virtual-register-based
delayed scavenging mechanism. As a result, these function parameters will not
be used, and can be removed.

Make all unnamed RegisterClass TreePatternNodes typed MVT::i32.
A register class can appear as a leaf TreePatternNode with and without a
name:
(COPY_TO_REGCLASS GPR:$src, F8RC)
In a named leaf node like GPR:$src, the register class provides type
information for the named variable represented by the node. The TypeSet
for such a node is the set of value types that the register class can
represent.
In an unnamed leaf node like F8RC above, the register class represents
itself as a kind of immediate. Such a node has the type MVT::i32,
we'll never create a virtual register representing it.
This change makes it possible to remove the special handling of
COPY_TO_REGCLASS in CodeGenDAGPatterns.cpp.
