d45eddd214 Revert the earlier change that removed the M_REMATERIALIZABLE machine 
instruction flag, and use the flag along with a virtual member function
hook for targets to override if there are instructions that are only
trivially rematerializable with specific operands (i.e. constant pool
loads).

82a87a0172 Replace M_REMATERIALIZIBLE and the newly-added isOtherReMaterializableLoad 
with a general target hook to identify rematerializable instructions. Some
instructions are only rematerializable with specific operands, such as loads
from constant pools, while others are always rematerializable. This hook
allows both to be identified as being rematerializable with the same
mechanism.

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.

f52e2618f3 If we want to emit things in enum order, use getInstructionsByEnumValue to 
get the order, don't compute it ourselves.

Don't emit stuff like (14<<0), emit 14 instead.

Don't attempt to get target properties for builtin instructions.

8d30c23d26 Emit this: 
static const TargetOperandInfo OperandInfo6[] = { { &PPC32::CRRCRegClass }, { 0 }, };

instead of this:

static const TargetOperandInfo OperandInfo6[] = { { PPC32::CRRCRegisterClass }, { 0 }, };

For operand information, which does not require dynamic (startup-time)
initialization.

a3ac88d8ab 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.
