  Changed paths:
    M libc/src/__support/FPUtil/Hypot.h
    M libc/src/math/generic/CMakeLists.txt

  Log Message:
  -----------
  [libc] Use get_round() instead of floating point tricks in generic hypot implementation.

The floating point tricks used to get rounding mode require -frounding-math flag, which behaves differently on aarch64.  Reverting back to use get_round instead.
