Update to use new syntax and actually check for the right failure by looking at
the error message.

Make insert_subreg a two-address instruction, vastly simplifying LowerSubregs pass. Add a new TII, subreg_to_reg, which is like insert_subreg except that it takes an immediate implicit value to insert into rather than a register.

Fix PR2138. Apparently any modification to a std::multimap (including remove entries for a different key) can invalidate multimap iterators.

Fix a number of encoding bugs. SSE 4.1 instructions MPSADBWrri, PINSRDrr, etc. have 8-bits immediate field (ImmT == Imm8).
