c4cfc20335 Fix problems in previous changes. This fixes several regressions last night.

3e30e40801 Checking in Chris's suggestions:
Added assert() to ensure symbol table is well formed.
Added code to remember the value that was found; resolving types can change
the symbol table and invalidate the value of the iterator.
Added comments to the ResolveTypes() function (mainly for my own benefit).
Please feel free to correct the comments if they are not accurate.

414e572f11 Significantly simplify constant emission by unifying the stuff which used to build up
strings with the stuff that used to print to an ostream directly.  We now NEVER build
up big strings, only to print them once they are formed.

a71b07eeca All DSGraphs keep a reference to the targetdata they are created with. This is
used to eliminate the hard coded, hacked in, sparc specific, global TargetData.
Changing the TargetData used to actually match the code fixes problems, and
eliminates a crash.

29f03b2d39 Including the symbol table in the FindUsedTypes analysis was the WRONG way

bec3b4ede1 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.

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.

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.
