so get rid of eh.selector.i64 and rename eh.selector.i32 to eh.selector.
Likewise for eh.typeid.for.  This aligns us with gcc, which always uses a
32 bit value for the selector on all platforms.  My understanding is that
the register allocator used to assert if the selector intrinsic size didn't
match the pointer size, and this was the reason for introducing the two
variants.  However my testing shows that this is no longer the case (I
fixed some bugs in selector lowering yesterday, and some more today in the
fastisel path; these might have caused the original problems).

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.

(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.

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.

legalization.

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.

llvm-svn: 84032

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.
