Remove Sparc support

Sadly, this is a dead architecture, without an official Debian port.
Rest in peace!

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.

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.

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.

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.
