96c1ade5c3 Maximally group commands. When all instructions within a command set have a
series of identical commands, handle them all with one switch.  In the case
of the x86 at&t asm printer, only 3 switches are needed for all instructions.

191dd1f186 Handle the last operand more intelligently. When emitting the \n, also
return from the asmprinter to make the generated asmprinter both more
efficient and smaller.

b51ecd4dd9 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.

bdff5f95b9 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.

Other improvements coming.

ff3d80ff7e simple optimization: don't bother calling "exists" (which calls the syscall
"access").  Instead, just let the open call fail if the file doesn't exist.
This reduces the # syscalls executed.

fceb57a917 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.

6af022f255 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.
