dac9131e28 Preselection is _not_ a basicblock pass, because it adds global variables to 
the module.  This change converts it from being a basic block pass to being
a simple pass.  This allows elimination of the annotation and simplification
of the logic for moving constants into global variables.

d248652b8b When opcodes like ADD were split into reg. and immed. versions (ADDi and ADDr), 
this code wasn't fixed correctly so it missed copy operations that used ADDi.

648cbd9804 Only fails on the Sparc, only when run via the JIT. 
And yet, it's a failure in the ``LowerSwitch'' pass.

3ab71367d0 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.

43a5ff8d40 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.

b2acc51bb2 * 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.
