this that make me feel dirty, but it's no worse than the
old isel.  I'll clean up the parts I can do without ripping
out the old one next.

an *almost* always incorrect case.  This only does the lookahead
in the insanely unlikely case, so it shouldn't impact performance.

On this testcase:

struct foo {
}
typedef int x;

Before:

t.c:3:9: error: cannot combine with previous 'struct' declaration specifier
typedef int x;
        ^

After:

t.c:2:2: error: expected ';' after struct
}
 ^

When laying out vtables for virtual bases in construction vtables, we need to check if the vtable is a primary base in the layout class.

APInt.  Be certain to set the integer bit in an x87 extended-precision
significand so that we don't accidentally make a pseudo-NaN.

It gets its own implementation totally divorced from the (presumably
performance-sensitive) routines which parse into a uint64_t.

Add APInt::operator|=(uint64_t), which is situationally much better than
using a full APInt.

instead of sometimes making QNaNs and sometimes SNaNs depending on the
type.
