addition to forwards. Also, increase the maximum number of instructions
to scan, as it appears to help in a fair number of cases.

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.

Also fixed a couple of coding style things that crept in.  And added more
to the temporary hacked up ARMAsmParser::MatchInstruction() method for testing.

Teach basic AA about PHI nodes. If all operands of a phi NoAlias another value than it's safe to declare the PHI NoAlias the value. Ditto for MustAlias.

multiple instructions, the expansion is done during selection so there is
no need to do anything special during legalization.

Do not check use_empty() before replaceAllUsesWith(). This gives ValueHandles a chance to get properly updated.

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.

Provide a mode for ImmutableMap/ImmutableSet to not automatically canonicalize the internal functional AVL trees.  This should speedup clients that use ImmutableMap/ImmutableSet but don't require fast comparisons of maps.
