c2d60abf52 X86: Distinguish between the rep and repe prefixes. 
STOS and MOVS only accept the rep prefix which always loops until rcx becomes
0. The other string instructions accept repe (same encoding as rep) and repne
which also check the condition code flags each iteration.

4049c9f76a X86: Put ldst into the microcode (the earlier changeset didn't really). 
Also clean things up as much as possible so that faulting won't break an
instruction. More microops which verify addresses are needed.
