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.

1) -fwritable-string does affect the non-utf16 version of cfstrings
just not the utf16 ones.
2) utf16 strings should always be marked constant, as the __TEXT segment
is readonly.
3) The name of the global doesn't matter, remove it from TargetInfo.
4) Trust the asmprinter to drop cstrings into the right section, like llvmgcc does now.

'CVPixelBufferCreateWithPlanarBytes()' and
'CVPixelBufferCreateWithBytes' (Core Video API) can indirectly release
a pixel buffer object via a callback.

(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.

unknown type name, e.g.,
foo::bar x;
when "bar" does not refer to a type in "foo".
With this change, the parser now calls into the action to perform
diagnostics and can try to recover by substituting in an appropriate
type. For example, this allows us to easily diagnose some missing
"typename" specifiers, which we now do:
test/SemaCXX/unknown-type-name.cpp:29:1: error: missing 'typename'
prior to dependent type name 'A<T>::type'
A<T>::type A<T>::f() { return type(); }

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