Correct regressions with --with-float={soft,softfp} in the arm backend

* lib/jit_arm.c: Correct use of wrong argument offset variable in armv7l or float/double argument for varargs function in armv7hl. Correct jit_getarg* logic in software float mode to match expected behavior in other backends, that is, if a function is not called, it is safe to use a few lightning calls before a next jit_getarg* call, as done in the test case check/stack.tst. The proper solution should be to extend the parser in lib/lightning.c to check if there is some float operation that will call some (libgcc?) function, but software float arm should be a very uncommon backend for lightning, so, just load the already in place arguments saved to stack, assuming the register argument was clobbered (what should not be the case most times...).
