Steal bits from the asm string index to use for operand information. On both
...
x86 and ppc, this gets us 4 more bits to play with, since the string indices
both only use 12 bits.

Completely change the structure of the generated asmprinter to be more table
...
based and less switch-statements-with-hundreds-of-cases based. This shrinks
the x86 asmprinters to about 1/3 their previous size.

Reduce instruction selection code size and stack frame size by factoring
...
code that emit target specific nodes into emit functions that are uniquified
and shared among selection routines.
e.g. This reduces X86ISelDAGToDAG.o (release) from ~2M to ~1.5M. Stack frame
size of Select_store from ~13k down to ~8k.
This is the first step. Further work to enable more sharing will follow.

Emit the string information for the asm writer as a single large string

and index into it, instead of emitting it like this:
static const char * const OpStrs[] = {
"PHINODE\n", // PHI
0, // INLINEASM
"adc ", // ADC32mi
"adc ", // ADC32mi8
...
The old way required thousands of relocations that slows down link time and
dynamic load times.
This also cuts about 10K off each of the X86 asmprinters, and should shrink
the others as well.
