crx.md: Make doloop_end pattern usage controllable via mloop-nesting=<max-nesting>...

* config/crx/crx.md: Make doloop_end pattern usage controllable
via mloop-nesting=<max-nesting> command line switch. Make sure
the combiner cannot use doloop_end_<mode> in an illegal way.
* config/crx/crx.c: Use regs up to r6 for argument passing.
Refine crx_address_cost (non cst4 displacements are expensive).
* config/crx/crx.opt: Add switch for mloop-nesting=.
