Remove the LoadHiAddr pseudo-instruction.

in the LLVM code generator sense (they are calls). Don't mark them as such,
which fixes the regressions on the ppc tester last night

register. Added support in the .td file for the g5-specific variant
of cr -> gpr moves that executes faster, but we currently don't
generate it.

This can generate considerably shorter code, reducing the size of crafty
by almost 1%. Also fix the printing of mcrf. The code is currently
disabled until it gets a bit more testing, but should work as-is.

Refactor how . instructions are handled. In particular, instead of passing
the RC flag all the way up the inheritance hierarchy, just make a new tblgen
class 'DOT' which can be added to an instruction definition.
For example, instead of this:
-def AND : XForm_6<31, 28, 0, 0, 0, (ops GPRC:$rA, GPRC:$rS, GPRC:$rB),
-let Defs = [CR0] in
-def ANDo : XForm_6<31, 28, 1, 0, 0, (ops GPRC:$rA, GPRC:$rS, GPRC:$rB),
- "and. $rA, $rS, $rB">;
We now have this:
+def AND : XForm_6<31, 28, 0, 0, (ops GPRC:$rA, GPRC:$rS, GPRC:$rB),
"and $rA, $rS, $rB">;

Have LegalizeDAG handle SREM and UREM for us
Codegen SDIV and UDIV by constant as a multiply by magic constant instead
of integer divide, which is very slow.

to save and restore the LR register on entry and exit of a leaf function
that needed to access globals or the constant pool. This should hopefully
fix oscar from sending the PPC tester spinning out of control.

The decimal value given in the manual (8 or 9) really needs to be multiplied by
a factor of 32 because of the group of 5 zero bits after the register code.

flag rotate left word immediate then mask insert (rlwimi) as a two-address
instruction, and update the ISel usage of the instruction accordingly.
This will allow us to properly schedule rlwimi, and use it to efficiently
codegen bitfield operations.

1. Fix an illegal argument to getClassB when deciding whether or not to
sign extend a byte load.
2. Initial addition of isLoad and isStore flags to the instruction .td file
for eventual use in a scheduler.
3. Rewrite of how constants are handled in emitSimpleBinaryOperation so
that we can emit the PowerPC shifted immediate instructions far more
often. This allows us to emit the following code:
int foo(int x) { return x | 0x00F0000; }
_foo:
.LBB_foo_0: ; entry
; IMPLICIT_DEF
