Fix Issue 12164 - Function returning ptrdiff_t.min in 64-bit returning 0 when
-O is set

The trick used to optimize ?const:const doesn't work when you can't actually
express the value as immediates.  They were silently truncated leading to
incorrect results.

Values were also truncated due to a typo.
