no visible functionality change, but enables a future patch where node creation
will update the CFG if it decides to create an unconditional rather than a conditional branch.

83ec4b6711 Wrap MVT::ValueType in a struct to get type safety 
and better control the abstraction.  Rename the type
to MVT.  To update out-of-tree patches, the main
thing to do is to rename MVT::ValueType to MVT, and
rewrite expressions like MVT::getSizeInBits(VT) in
the form VT.getSizeInBits().  Use VT.getSimpleVT()
to extract a MVT::SimpleValueType for use in switch
statements (you will get an assert failure if VT is
an extended value type - these shouldn't exist after
type legalization).
This results in a small speedup of codegen and no
new testsuite failures (x86-64 linux).

17183ab973 If BitWidth equals to ShtAmt, the RHSKnownZero[BitWidth-ShiftAmt-1] will 
crash the opt. Just fix this.

bfde7d6b9e As comments said, for negative value, the arithmetic 
over-shift-right should return -1. So here it should be signed-extended,
