The callers of ParseStructDeclaration are not expecting it to

eat the terminating ;. Fix one place where it did, allowing this
to compile without error:
struct x {
int a;
union {
int b;
float c;
};
int d;
};

Fix a parser bug on labeled inline asm stmts, allowing us

to parse stuff like:
asm volatile("1: rex64/fxrstor (%[fx])\n\t"

" jmp 2b\n"

The guaranteed alignment of ptr+offset is only the minimum of
...
of offset and the alignment of ptr if these are both powers of
2. While the ptr alignment is guaranteed to be a power of 2,
there is no reason to think that offset is. For example, if
offset is 12 (the size of a long double on x86-32 linux) and
the alignment of ptr is 8, then the alignment of ptr+offset
will in general be 4, not 8. Introduce a function MinAlign,
lifted from gcc, for computing the minimum guaranteed alignment.
I've tried to fix up everywhere under lib/CodeGen/SelectionDAG/.
I also changed some places that weren't wrong (because both values
were a power of 2), as a defensive change against people copying
and pasting the code.
Hopefully someone who cares about alignment will review the rest
of LLVM and fix up the remaining places. Since I'm on x86 I'm
not very motivated to do this myself...
