- Added Sema::AddFactoryMethodToGlobalPool and Sema::AddInstanceMethodToGlobalPool and DenseMaps. This will allow us to efficiently lookup a method from a selector given no type information (for the "id" data type).
...
- Fixed some funky "}
else {" indentation in Sema::ActOnAddMethodsToObjcDecl(). I'd prefer we stay away from this style...it wastes space and isn't any easier to read (from my perspective, at least:-)
- Changed Parser::ParseObjCInterfaceDeclList() to only call Action::ActOnAddMethodsToObjcDecl() when it actually has methods to add (since most interface have methods, this is a very minor cleanup).

Enhance the truncstore optimization code to handle shifted
...
values and propagate demanded bits through them in simple cases.
This allows this code:
void foo(char *P) {
strcpy(P, "abc");
}
to compile to:
_foo:
ldrb r3, [r1]
ldrb r2, [r1, #+1]
ldrb r12, [r1, #+2]!
ldrb r1, [r1, #+1]
strb r1, [r0, #+3]
strb r2, [r0, #+1]
strb r12, [r0, #+2]
strb r3, [r0]
bx lr
instead of:
_foo:
ldrb r3, [r1, #+3]
ldrb r2, [r1, #+2]
orr r3, r2, r3, lsl #8
ldrb r2, [r1, #+1]
ldrb r1, [r1]
orr r2, r1, r2, lsl #8
orr r3, r2, r3, lsl #16
strb r3, [r0]
mov r2, r3, lsr #24
strb r2, [r0, #+3]
mov r2, r3, lsr #16
strb r2, [r0, #+2]
mov r3, r3, lsr #8
strb r3, [r0, #+1]

Local spiller optimization:

Turn this:
movswl %ax, %eax
movl %eax, -36(%ebp)
xorl %edi, -36(%ebp)
into
movswl %ax, %eax
xorl %edi, %eax
movl %eax, -36(%ebp)
by unfolding the load / store xorl into an xorl and a store when we know the
value in the spill slot is available in a register. This doesn't change the
number of instructions but reduce the number of times memory is accessed.
Also unfold some load folding instructions and reuse the value when similar
situation presents itself.

Replace one FIXME with another. We handle protocols just fine now. The ObjC decl will only be 0 when we have an error on the ObjC decl. I would prefer we pass in a decl that is marked as invalid.
