483e880b10 Fix byte stores on x86-32 
Also on x86-32, use RBX as the tmp register, as it is byte-addressable.

42bc762d26 Add facility to enter and leave JIT ABI 
This allows us to save and restore callee-save temporaries, i.e. RBP on
32-bit x86.  Otherwise it's a disaster shuffling stack arguments using
temporaries.

9906cd5f84 Remove most __X64_32 code 
The x32 ABI (i.e., amd64 with 32-bit pointers) is mostly a C language
question.  From a JIT perspective it mostly looks just like amd64.  We
can fix any differences in a followup, but x32 is also a pretty dead
ABI, so I feel OK with this.

24950994ef Simplify 64/32 concerns in x86-cpu.c 
* lightening/x86-cpu.c (il): Take a uint64_t.  It's only called this
  way.
(imovi): Remove some x64_32 conditions; they seem bogus.

e29977a82b Simplify register representation even more 
The register structures just contain the regno.  Since the only flag is
the callee-save flag, we can punt that to a separate per-backend,
per-target predicate.

2602f17fb4 Simplify register representation again 
There's only one flag, "callee-save".  Also the regno range is limited
to 0-63 inclusive, to allow for cheap register sets as uint64_t values.

99e5672726 Renumber x86 registers 
Now that there's no hazard to using a register used for passing
arguments, renumber to give JIT_R/JIT_F/JIT_V names to all registers.

Choose a temp register that's not used for passing arguments.  Our
previous choice was an argument register (doh!) which made function
calls with many arguments fail.

ddd66a2f34 Simplify register representation 
Instead of JIT_R0 being a wrapped index into a table which then gives
the regno and class, just have JIT_R0 be the wrapped regno and class.

f348b8ed6d Change headers and files to be named "lightening" instead of "jit" 
This improves integration with other projects.  Like for example Guile
already has files named jit.c and jit.h; it's easier to manage if
lightening uses its own file names.
