Build and pass all tests on 32 and 64 bit sparc

Browse source 
* include/lightning/jit_private.h: Add new register classes to
	flag float registers and double only registers, required for sparc64
	where only low 32 bit fpr registers can be used for single precision
	operations.
	Add new 128 bit jit_regset_t type for sparc64 register set.

	* include/lightning/jit_sparc.h, lib/jit_sparc-cpu.c, lib/jit_sparc-fpu.c,
	lib/jit_sparc-sz.c, lib/jit_sparc.c: Update for 64 bits sparc.

	* lib/lightning.c: Update for new jit_regset_t required for sparc64.
