Inst pattern EQV: (set GPRC:i32:$rT, (xor (xor GPRC:i32:$rA, GPRC:i32:$rB), (imm)<<Predicate_immAllOnes>>))
we now fully infer:
Inst pattern EQV: (set:void GPRC:i32:$rT, (xor:i32 (xor:i32 GPRC:i32:$rA, GPRC:i32:$rB), (imm:i32)<<Predicate_immAllOnes>>))

be checked in as any other LLVM source so that platforms without convenient
access to flex/bison can be compiled. From now on, if you change a .y or
.l file you *must* also commit the generated .cpp and .h files.

When emitting implicit use/def lists, only emit each unique list once. Though
...
LLVM is able to merge identical static const globals, GCC isn't, and this caused
some bloat in the generated data. This has a marginal effect on PPC, shrinking
the implicit sets from 10->4, but shrinks X86 from 179 to 23, a much bigger
reduction.
This should speed up the register allocator as well by reducing the dcache
footprint for this static data.

This is the final big of factoring. This shares cases in suboperand
...
differences, which means that identical instructions (after stripping off
the first literal string) do not run any different code at all. On the X86,
this turns this code:

After this, the generated asmwriters look pretty much as though they were
generated by hand. This shrinks the X86 asmwriter.inc files from 55101->39669
and 55429->39551 bytes each, and PPC from 16766->12859 bytes.

Implement *even more* factoring. In particular, if all of the instruction
...
strings starts out with a constant string, we emit the string first, using
a table lookup (instead of a switch statement).
Because this is usually the opcode portion of the asm string, the differences
between the instructions have now been greatly reduced. This allows many
more case statements to be grouped together.
This patch also allows instruction cases to be grouped together when the
instruction patterns are exactly identical (common after the opcode string
has been ripped off), and when the differing operand is a MachineInstr
operand that needs to be formatted.
The end result of this is a mean and lean generated AsmPrinter!

Implement factoring of instruction pattern strings. In particular, instead of
...
emitting code like this:
case PPC::ADD: O << "add "; printOperand(MI, 0, MVT::i64); O << ", "; prin
tOperand(MI, 1, MVT::i64); O << ", "; printOperand(MI, 2, MVT::i64); O << '\n
'; break;
case PPC::ADDC: O << "addc "; printOperand(MI, 0, MVT::i64); O << ", "; pr
intOperand(MI, 1, MVT::i64); O << ", "; printOperand(MI, 2, MVT::i64); O << '
\n'; break;
case PPC::ADDE: O << "adde "; printOperand(MI, 0, MVT::i64); O << ", "; pr
intOperand(MI, 1, MVT::i64); O << ", "; printOperand(MI, 2, MVT::i64); O << '
\n'; break;
...
Emit code like this:
case PPC::ADD:
case PPC::ADDC:
case PPC::ADDE:
...
switch (MI->getOpcode()) {
case PPC::ADD: O << "add "; break;
case PPC::ADDC: O << "addc "; break;
case PPC::ADDE: O << "adde "; break;
...
}
printOperand(MI, 0, MVT::i64);
O << ", ";
printOperand(MI, 1, MVT::i64);
O << ", ";
printOperand(MI, 2, MVT::i64);
O << "\n";
break;
This shrinks the PPC asm writer from 24785->15205 bytes (even though the new
asmwriter has much more whitespace than the old one), and the X86 printers shrink
quite a bit too. The important implication of this is that GCC no longer hits swap
when building the PPC backend in optimized mode. Thus this fixes PR448.

Seperate asmstring parsing from emission. This allows the code to be simpler
...
and more understandable. It also allows us to do simple things like fold
consequtive literal strings together. For example, instead of emitting this
for the X86 backend:
O << "adc" << "l" << " ";
we now generate this:
O << "adcl ";
*whoa* :)
This shrinks the X86 asmwriters from 62729->58267 and 65176->58644 bytes
for the intel/att asm writers respectively.

Change MRegisterDesc::AliasSet, TargetInstrDescriptor::ImplicitDefs
...
and TargetInstrDescriptor::ImplicitUses to always point to a null
terminated array and never be null. So there is no need to check for
pointer validity when iterating over those sets. Code that looked
like:
if (const unsigned* AS = TID.ImplicitDefs) {
for (int i = 0; AS[i]; ++i) {
// use AS[i]
}
}
was changed to:
for (const unsigned* AS = TID.ImplicitDefs; *AS; ++AS) {
// use *AS
}

operand (unless it's annul or predict). Now we only consider fields to be
operands if they are uninitialized AND used in the "Inst" field.
