8a336ec771 First cut at the LLVM Makefile Guide. There's lots to correct and lots more 
to write, but this is all my brain can muster for tonight.

bd6a01c3ef DForm_1, particularly used by store instructions, needs the immediate operand to 
be listed second as that is how the instructions are usually created (and is the
correct asm syntax) so that it's assembled correctly from its constituents

e4ae05e099 Fix the SPR field for MTLR, MFLR, MTCTR, and MFCTR instructions. 
The decimal value given in the manual (8 or 9) really needs to be multiplied by
a factor of 32 because of the group of 5 zero bits after the register code.

91ef127999 Kill casts from integer types to unsigned byte, when the cast was only used 
as the shift amount operand to a shift instruction.  This was causing us to
emit unnecessary clear operations for code such as:
int foo(int x) { return 1 << x; }

ffc5ff3ca9 Pull in Target.td using absolute path from source root instead of relative path; 
this allows us to have sub-targets whose depth in the tree is not the same as it
is for the standard X86/PowerPC/Sparc.

9514a75e36 * Added basic support for JITing functions, basic blocks, instruction encoding, 
including registers, constants, and partial support for global addresses
* The JIT is disabled by default to allow building llvm-gcc, which wants to test
  running programs during configure

0ba9295e3c Small performance improvement in generated C code: 
Instead of unconditionally copying all phi node values into temporaries for
all successor blocks, generate code that will determine what successor
block will be called and then copy only those phi node values needed by
the successor block.

This seems to cut down namd execution time from being 8% higher than GCC to
4% higher than GCC.

9113553178 * Add baseline structural JIT code, but disable the JIT to allow llvm-gcc builds 
- Support added for functions, basic blocks, constant pool, constants,
    registers, and some basic support for globals, all untested
* Turn assert()s into abort()s so that unimplemented functions fail in release

49e38c2185 Initial implementation of the strength reduction for GEP instructions in 
loops.  This optimization is not turned on by default yet, but may be run
with the opt tool's -loop-reduce flag.  There are many FIXMEs listed in the
code that will make it far more applicable to a wide range of code, but you
have to start somewhere :)

This limited version currently triggers on the following tests in the
MultiSource directory:
pcompress2: 7 times
cfrac: 5 times
anagram: 2 times
ks: 6 times
yacr2: 2 times
