681a33e26d Another BasicAA fix. If a value does not alias a GEP's base pointer, then it 
cannot alias the GEP. GEP pointer alias rule states this clearly:
A pointer value formed from a getelementptr instruction is associated with the
addresses associated with the first operand of the getelementptr.

1b1764b3f7 Make isSafeToClobberEFLAGS more aggressive. Teach it to scan backwards 
(for uses marked kill and defs marked dead) a few instructions in
addition to forwards. Also, increase the maximum number of instructions
to scan, as it appears to help in a fair number of cases.

9ba0e2ba87 This remat entry is basically done. There are hooks to allow targets 
to remat non-load instructions as loads, and the remat code now uses
the UnmodeledSideEffects flags, MachineMemOperands, and similar things
to decide which instructions are valid for rematerialization.

73d64a6fd3 NEON VLD/VST are now fully implemented. For operations that expand to 
multiple instructions, the expansion is done during selection so there is
no need to do anything special during legalization.

3a66a68b0c Introduce new convenience methods for sign extending or 
truncating an SDValue (depending on whether the target
type is bigger or smaller than the value's type); or zero
extending or truncating it.  Use it in a few places (this
seems to be a popular operation, but I only modified cases
of it in SelectionDAGBuild).  In particular, the eh_selector
lowering was doing this wrong due to a repeated rather than
inverted test, fixed with this change.
