fd447eff22 The FoldingSet hash data includes pointer values, so it isn't
determinstic. Instead, give SCEV objects an arbitrary sequence
number.

4d52c6d622 Optimize ScalarEvolution's SCEVComplexityCompare predicate: don't go
scrounging through SCEVUnknown contents and SCEVNAryExpr operands;
instead just do a simple deterministic comparison of the precomputed
hash data.

Also, since this is more precise, it eliminates the need for the slow
N^2 duplicate detection code.

22a5b29820 Create new accessors to get arguments for call/invoke instructions. It breaks
encapsulation to force the users of these classes to know about the internal
data structure of the Operands structure. It also can lead to errors, like in
the MSIL writer.

6de07178e1 Keep track of the call instructions whose clobber lists were skipped during fast

Process all of the clobber lists at the end of the function, marking the
registers as used in MachineRegisterInfo.

This is necessary in case the calls clobber callee-saved registers (sic).

f62546ab04 Fixed a bug during widening where we would avoid legalizing a node. When we
replace an OpA with a widened OpB, it is possible to get new uses of OpA due to CSE
when recursively updating nodes.  Since OpA has been processed, the new uses are
not examined again.  The patch checks if this occurred and it it did, updates the
new uses of OpA to use OpB.
