Fix PR61657 (undefined behavior in loop-iv.c)

bootstrap-ubsan shows:
 loop-iv.c:2626:14: runtime error: signed integer overflow: 9223372036854775806 - -9223372036854775808 cannot be represented in type 'long int'

Fixed by moving the variables in question from signed to unsigned.

PR rtl-optimization/61657
* loop-iv.c (iv_number_of_iterations): Declare up and down as
unsigned. Remove superflous uint64_t cast.

xtensa: fix _Unwind_GetCFA

Returning context->cfa in _Unwind_GetCFA makes CFA point one stack frame
higher than what was actually used by code at context->ra. This results
in invalid CFA value in signal frames and premature unwinding completion
in forced unwinding used by uClibc NPTL thread cancellation.
Returning context->sp from _Unwind_GetCFA makes all CFA values valid and
matching code that used them.
