Rework PPC64 calls. Now we have a LR8/CTR8 register which the PPC64 calls

clobber. This allows LR8 to be save/restored correctly as a 64-bit quantity,
instead of handling it as a 32-bit quantity. This unbreaks ppc64 codegen when
the code is actually located above the 4G boundary.

Fix a bug handling nodes with variable arguments. The code was fixed to assume
...
that there were two input operands before the variable operand portion. This
*happened* to be true for all call instructions, which took a chain and a
destination, but was not true for the PPC BCTRL instruction, whose destination
is implicit.
Making this code more general allows elimination of the custom selection logic
for BCTRL.

lower "X = seteq Y, Z" to '(shr (ctlz (xor Y, Z)), 5)' instead of
...
'(shr (ctlz (sub Y, Z)), 5)'.
The use of xor better exposes the operation to bit-twiddling logic in the
dag combiner. For example, this:
typedef struct {
unsigned prefix : 4;
unsigned code : 4;
unsigned unsigned_p : 4;
} tree_common;
int foo(tree_common *a, tree_common *b) {
return a->code == b->code;
}
Now compiles to:
_foo:
lwz r2, 0(r4)
lwz r3, 0(r3)
xor r2, r3, r2
rlwinm r2, r2, 28, 28, 31
cntlzw r2, r2
srwi r3, r2, 5
blr
instead of:
_foo:
lbz r2, 3(r4)
lbz r3, 3(r3)
srwi r2, r2, 4
srwi r3, r3, 4
subf r2, r2, r3
cntlzw r2, r2
srwi r3, r2, 5
blr
saving a cycle.
