87db26ad2c 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.

78decbdb9d Explicitly pass in the "unknown" debug location. This is probably not 
correct. We need more infrastructure before we can get the DebugLoc info for
these instructions.

5b177df8e9 Create DebugLoc information in FastISel. Several temporary methods were 
created. Specifically, those BuildMIs which use
"DebugLoc::getUnknownLoc()". I'll remove them soon.

0103631cce 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.

cac6cf74f9 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.

74179a9dde 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).
