x86: Add microop for fence
...
This patch adds a new microop for memory barrier. The microop itself does
nothing, but since it is marked as a memory barrier, the O3 CPU should flush
all the pending loads and stores before the fence to the memory system.

X86: Make the halt microop non-speculative.
...
Executing this microop makes the CPU halt even if it was misspeculated.

X86: Get rid of the flagless microop constructor.
...
This will reduce clutter in the source and hopefully speed up compilation.

X86: Consolidate extra microop flags into one parameter.
...
This single parameter replaces the collection of bools that set up various
flavors of microops. A flag parameter also allows other flags to be set like
the serialize before/after flags, etc., without having to change the
constructor.
