0518651bfd Expose API to bless function pointers 
On ARMv7, we need to set the low bit to indicate that we're in
thumb-land.

9d4185af2b Remove jit_nop 
Instead, jit_align will call nop() internally.  You can't nop 3 bytes on
most architectures.

5b8262e804 Rework register saving to avoid push/pop 
Push and pop are not well supported on AArch64, so we might as well just
bump the stack pointer once and fill in by offset.

570f361c6c Remove Sparc support 
Sadly, this is a dead architecture, without an official Debian port.

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.

Also, fix alignment to be in bytes rather than bits.  Oops!
