Subject: [PATCH 58/81] Ensure calculations happen with desired rounding mode
in y1lf128
math/test-float128-y1 fails on x86_64 and ppc64el with gcc 12 and -O3,
because code inside a block guarded by SET_RESTORE_ROUNDL is being moved
after the rounding mode has been restored. Use math_force_eval to
prevent this (and insert some math_opt_barrier calls to prevent code
from being moved before the rounding mode is set).
Fixes #29463
Reviewed-By: Wilco Dijkstra <Wilco.Dijkstra@arm.com>
(cherry picked from commit 2b274fd8c9c776cf70fcdb8356e678ada522a7b0)
