when changing Instruction.def.  :(

c4f8226aaf Emit x86 instructions for: A = B op C, where A and B are 16-bit registers, 
C is a constant which can be sign-extended from 8 bits without value loss,
and op is one of: add, sub, imul, and, or, xor.

This allows the JIT to emit the one byte version of the constant instead of
the two or 4 byte version.  Because these instructions are very common, this
can save a LOT of code space.  For example, I sampled two benchmarks, 176.gcc
and 254.gap.

BM        Old     New    Reduction
176.gcc 2673621 2548962  4.89%
254.gap  498261  475104  4.87%

Note that while the percentage is not spectacular, this did eliminate
124.6 _KILOBYTES_ of codespace from gcc.  Not bad.

Note that this doesn't effect the llc version at all, because the assembler
already does this optimization.

5a577c0b28 * Rename X86::IMULr16 -> X86::IMULrr16 
* Implement R1 = R2 * C where R1 and R2 are 32 or 16 bits. This avoids an
  extra copy into a register, reducing register pressure.

3d519c7bab * Multiplications by 2^X are turned into shifts. This factors code out of the 
getelementptr code path for use by other code paths (like malloc and alloca).
* Optimize comparisons with zero
* Generate neg, not, inc, and dec instructions, when possible.

This gives some code size wins, which might translate into performance.  We'll
see tommorow in the nightly tester.

27798b47fb Without this option, the -run-llc mode does not work with shared objects at 
all, making it pointless for use with the code generator debugger.  With it,
it works like a charm.
