Implement jit_allocar for dynamic stack allocation

* include/lightning.h, include/lightning/jit_private.h, lib/jit_aarch64-cpu.c, lib/jit_aarch64.c, lib/jit_alpha-cpu.c, lib/jit_alpha.c, lib/jit_arm-cpu.c, lib/jit_arm.c, lib/jit_hppa-cpu.c, lib/jit_hppa.c, lib/jit_ia64-cpu.c, lib/jit_ia64.c, lib/jit_mips-cpu.c, lib/jit_mips.c, lib/jit_ppc-cpu.c, lib/jit_ppc.c, lib/jit_s390-cpu.c, lib/jit_s390.c, lib/jit_sparc-cpu.c, lib/jit_sparc.c, lib/jit_x86-cpu.c, lib/jit_x86.c: Implement the new jit_allocar(offs, size) interface, that receives two integer registers arguments, allocates space dynamically in the stack, returns the offset in the first argument, and uses the second argument for the size in bytes of the memory to be allocated. * check/allocar.ok, check/allocar.tst: New files implementing test cases for the new jit_allocar interface. * check/Makefile.am, check/lightning.c: Update for the new test case and interface. * doc/body.texi: Add documentation of the new interface.
