a6dc9fb745 Fix a bug handling instructions, like blr, which just consist of a text 
string.  The return value of printInstruction should be true for these.

195bb4a7b0 Fix case where identical cases were not detected across case #0, because 
instructions not handled would have a case value of #0, throwing things off.
This marginally shrinks the X86 asmprinter, but shrinks the sparc asmwriter
by 25 lines.

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.

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.

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.

186fb7d131 Don't require src/dst patterns to be able to fully resolve their types, 
because information about one can help refine the other.  This allows us to
write:

def : Pat<(i32 (extload xaddr:$src, i8)),
          (LBZX xaddr:$src)>;

as:

def : Pat<(extload xaddr:$src, i8),
          (LBZX xaddr:$src)>;

because tblgen knows LBZX returns i32.

a354849c27 Make sure to use the result of the pattern to infer the result type of the 
instruction, and the result type of the instruction to refine the pattern.
This allows us to write things like this:

as:
def : Pat<(v2i64 (bitconvert (v16i8 VR128:$src))), (VR128:$src)>

8d3af5e7d0 Instructions with variable operands (variable_ops) can have a number required 
operands. e.g.
def CALL32r : I<0xFF, MRM2r, (ops GR32:$dst, variable_ops),
                "call {*}$dst", [(X86call GR32:$dst)]>;
TableGen should emit operand informations for the "required" operands.

Added a target instruction info flag M_VARIABLE_OPS to indicate the target
instruction may have more operands in addition to the minimum required
operands.
