Completely rewrite libcall insertion by the legalizer, providing the
...
following handy-dandy properties:
1. it is always correct now
2. it is much faster than before
3. it is easier to understand
This implementation builds off of the recent simplifications of the
legalizer that made it single-pass instead of iterative.
This fixes JM/lencod, JM/ldecod, and
CodeGen/Generic/2006-02-12-InsertLibcall.ll (at least on PPC).

Three changes:
...
1. Teach GetConstantInType to handle boolean constants.
2. Teach instcombine to fold (compare X, CST) when X has known 0/1 bits.
Testcase here: set.ll:test22
3. Improve the "(X >> c1) & C2 == 0" folding code to allow a noop cast
between the shift and and. More aggressive bitfolding for other reasons
was turning signed shr's into unsigned shr's, leaving the noop cast in
the way.
