Debug Info: Relax assertion in isUnsignedDIType() to allow floats to be
described by integer constants. This is a bit ugly, but if the source
language allows arbitrary type casting, the debug info must follow suit.
For example:
void foo() {
float a;
*(int *)&a = 0;
}
For the curious: SROA replaces the float alloca with an i32 alloca, which
is then optimized away and described via dbg.value(i32 0, ...).
