45e94d68d7 Don't bother hoisting out a "cheap" instruction if all of its uses are PHIs. LICM "cheap" instructions are not particularly beneficial to start with. This will just end up making the copies harder to coalesce.

9b61f33351 For now, only hoist re-materilizable instructions. LICM will increase register pressure. We want to avoid spilling more instructions if it's possible.

95c5f05641 Fix PR3411. When replacing values, nodes are analyzed 
in any old order.  Since analyzing a node analyzes its
operands also, this can mean that when we pop a node
off the list of nodes to be analyzed, it may already
have been analyzed.

a7ce741ff0 Use the SubclassData field to hold ExtType, isTrunc, and MemIndexedMode 
information. This eliminates the need for the Flags field in MemSDNode,
so this makes LoadSDNode and StoreSDNode smaller. Also, it makes
FoldingSetNodeIDs for loads and stores two AddIntegers smaller.

Live interval reconstruction needs to account for this, and scour its maps to
prevent dangling references.

b0d5cdd52e Fix PR3453 and probably a bunch of other potential 
crashes or wrong code with codegen of large integers:
eliminate the legacy getIntegerVTBitMask and
getIntegerVTSignBit methods, which returned their
value as a uint64_t, so couldn't handle huge types.

92abc62399 Fix PR3401: when using large integers, the type 
returned by getShiftAmountTy may be too small
to hold shift values (it is an i8 on x86-32).
Before and during type legalization, use a large
but legal type for shift amounts: getPointerTy;
afterwards use getShiftAmountTy, fixing up any
shift amounts with a big type during operation
legalization.  Thanks to Dan for writing the
original patch (which I shamelessly pillaged).
