  Log Message:
  -----------
  [libc] Add implementations of remquo[f|l] and remainder[f|l].

The implementation is not fully standards compliant in the sense that
errno is not set on error, and floating point exceptions are not raised.

Subnormal range and normal range are tested separately in the tests.
