Hi all,
This patch has been updated to conditionally fold the specified math functions
only when using MPFR version 4.2.0 or newer.
To accompany this change, the test case now utilizes `__builtin_constant_p` to
determine whether to execute the tests against the folded functions.
Let me know if t

Hello world,
This patch partially handled PR118592.
This patch builds upon r16-710-g591d3d02664c7b and r16-711-g89935d56f768b4. It
introduces middle-end optimizations, such as constant folding, for our
trigonometric pi-based function built-ins.
For MPFR versions older than 4.2.0, we've included
