01e64b5eef Bug fix in folding getElementPtr instructions: don't fold one into
a predecessor if it has a non-zero first index and the predecessor
ends with a struct index.

18e3c4ff50 - Change getelementptr instruction to use long indexes instead of uint
indexes for sequential types.

3ce5b343c5 - Renamed Type::isIntegral() to Type::isInteger()
- Added new method Type::isIntegral() that is the same as isInteger, but
    also accepts bool.

3190395e10 Moved code here to extract memory instruction indices and to check
whether FoldGetElemNodes should be called.  This is machine-independent
but was in the Sparc directory.  This is in a new function: GetMemInstArgs.

3489677a7e Add function GetConstantValueAsUnsignedInt.
Fix 2 bugs in FoldGetElemChain so index vector is not modified
when no GEPs are folded in, and so a hasLeadingZero is computed
only for the last folded GEP, not the one after that if any.

are being converted over to Function.

34b17e8a37 1. Add a bottom-up pass on BURG trees that is used to fix constant operands.
Needs to be bottom up because constant values may be forward-substituted
   to their uses (i.e., into the parent in the BURG tree).
2. Move most of the constant-fixup code into machine-indepedent file
   InstrSelectionSupport.cpp.
