Make the alignedload and alignedstore patterns always require 16-byte
alignment. This way when they are used in the "Fs" instructions, in which
a vector instruction is used for a scalar purpose, they can still require
the full vector alignment. And add a regression test for this.

with StructReturn and ByVal, so make it so.

Verifier::visitFunction is suffering a combinatorial
explosion due to the number of mutually incompatible
attributes.  This patch tidies the whole thing up
using attribute masks.  While there I fixed some
small bugs: (1) the ByVal attribute tests cast a
type to a pointer type, which can fail.  Yes, the
fact it is of a pointer type is checked before,
but a failing check does not cause the program
to exit, it continues on outputting further errors;
(2) Nothing was checking that an sret attribute is
on the first parameter; (3) nothing was checking that
a function for which isStructReturn() is true has a
parameter with the sret attribute and vice-versa (I
don't think it is possible for this to go wrong, but
it seems right to check it).

#include <stdio.h>

int
main(void) {
        int test = 0;

        printf("Type is %s\n", (test >= 1 ? "short" : "char"));

        return (0);
}

It comes up with a diagnostic that's misleading upon first read.

t.c:7:36: error: incompatible operand types ('char *' and 'char *')
        printf("Type is %s\n", (test >= 1 ? "short" : "char"));

Add a MachineFunction pass, which runs post register allocation, that turns subreg insert/extract instruction into register copies. This ensures correct code gen if the coalescer isn't able to remove all subreg instructions.

Various improvements to Sema::ParseMemberReferenceExpr().

- Added source range support to Diag's.
- Used the new type predicate API to remove dealing with the canonical
type explicitly.
- Added Type::isRecordType().
- Removed some casts.
- Removed a const qualifier from RecordType::getDecl().
