Add the SubRegIndex TableGen class.
...
This is the beginning of purely symbolic subregister indices, but we need a bit
of jiggling before the explicit numeric indices can be completely removed.

improve type checking of SDNode operand count. This rejects all cases
...
where an incorrect number of operands is provided to an sdnode instead
of just a few cases.

finally remove the immAllOnesV_bc/immAllZerosV_bc patterns
...
and those derived from them. These are obnoxious because
they were written as: PatLeaf<(bitconvert). Not having an
argument was foiling adding better type checking for operand
count matching up with what was required (in this case,
bitconvert always requires an operand!)

teach tblgen to allow patterns like (add (i32 (bitconvert (i32 GPR))), 4),
...
transforming it into (add (i32 GPR), 4). This allows us to write type
generic multi patterns and have tblgen automatically drop the bitconvert
in the case when the types align. This allows us to fold an extra load
in the changed testcase.

fix CodeGenTarget::getRegisterVTs to not return the

same vt multiple times for a register. For example,
ECX is in 5 different i32 reg classes, just return
1 i32 instead of 5.

hoist some funky logic into CodeGenInstruction

from two places in CodeGenDAGPatterns.cpp, and
use it in DAGISelMatcherGen.cpp instead of using
an incorrect predicate that happened to get lucky
on our current targets.

continue pushing tblgen's support for nodes with multiple

produces one implicit def and one result instead of one or
the other when not at the root of the pattern.
