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.

* Spell "necessary" correctly

This increases the number of floating point constants that may be emitted
inline, and improves precision for global variable initializers which
can not be emitted in integer form.

* Fix isFPCSafeToPrint to find more constants safe to print, which it was
failing because ftostr was padding with leading space characters.
* Scan the entire module for global constants instead of each function at a
time. This has the advantage of allowing us to emit constants at global
scope instead of function scope. This speeds FP programs quite a bit.

Don't explicitly use $SourceDir to find the tblgen files. This causes make
...
some confusion when trying to generate files (it probably couldn't tell that
./file and $(SourceDir)/file may be the same file).
Now, just let VPATH find everything, and list the primary tblgen file first in
the list of dependencies so that we can just use $< to reference it in the make
rule.
This should hopefully fix the nightly tester.

Updated to find source files using VPATH. This makes writing build rules
...
much cleaner and easier.
Labeled .td as a suffix for tblgen files in Makefile.rules.
Modified build rules so that source files generated during the build are placed
in the build directory and not the source directory (and not in a Debug
directory). This makes the system cleaner and allows us to have a read-only
source tree.

Added some optimizations:
...
* Generate a single BA instead of 6-instruction JUMP if possible
(this occurs both in the creation and overwriting of the stub code)
* If possible, rewrite the ORIGINAL call to call the generated function
directly, thus bypassing the stub entirely
Also added some statistics on how often calls are overwritten and how often the
CompilationCallback is invoked.
