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.

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.

extra copy into a register, reducing register pressure.

* 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.
