76221cc874 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.

49946908b4 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.

a98883deaa More Neon clean-up: avoid the need for custom-lowering vld/st-lane intrinsics 
by creating TargetConstants during instruction selection instead of during
legalization.

959ec973ad More bits of the ARM target assembler for llvm-mc to parse immediates. 
Also fixed a couple of coding style things that crept in.  And added more
to the temporary hacked up ARMAsmParser::MatchInstruction() method for testing.

88df19e49a 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.

d4a35e9f36 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.

BasicBlocks, so that it doesn't blindly procede in the presence of
large individual BasicBlocks. This addresses a class of code-size
