versions of creation functions.  Eventually, the "insertion point" versions
of these should just be removed, we do have IRBuilder afterall.

Do a massive rewrite of much of pattern match.  It is now shorter and less
redundant and has several other widgets I will be using in other patches.
Among other changes, m_Div is renamed to m_IDiv (since it only matches
integer divides) and m_Shift is gone (it used to match all binops!!) and
we now have m_LogicalShift for the one client to use.

Enhance IRBuilder to have "isExact" arguments to things like CreateUDiv
and reduce redundancy within IRbuilder by having these methods chain to
each other more instead of duplicating code.

1. The encoding for the literal and immediate constant are different.

Implement support for custom target specific asm parsing of operands.

immediates) operand forms.

This commit implements only the generic support. The ARM specific modifications
will come next.

containing a 'ParserMethod' in its AsmOperandClass

A matcher function very similar (but lot more naive) to
MatchInstructionImpl scans the table. After the mnemonic match, the
features are checked and if the "to be parsed" operand index is
present in the mask, there's a real match. Then, a switch like the one

 case MCK_Coproc:
   return TryParseCoprocessorOperandName(Operands);

bonus to only add a bonus if we can inline a small function to devirtualize
