924464b03b Made the Requirements information its own major section and moved it
between the "Getting Started Quickly" and "Getting Started Slowly" sections.
:)
Removed some of the nit-picky requirements information (i.e. GNU tar and
GNU zip).
Attempted to compact the requirements information so that it is less scary.

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.
