X86: add ULL to 1's being shifted in 64-bit values

Some of the micro-ops weren't casting 1 to ULL before shifting,
which can cause problems.  On the perl makerand input this
caused some values to be negative that shouldn't have been.

The casts are done as ULL(1) instead of 1ULL to match others
in the m5 code base.
