Use PF_USED_MATH flag to mark whether the thread has accessed any FPSIMD
registers, so we could avoid saving and restroing FPSIMD registers until
threads access them. This may improve performance when lazy FPSIMD restore
is disabled.

Use PF_USED_MATH flag to mark whether the thread has accessed any FPSIMD
registers, so we could avoid saving and restroing FPSIMD registers until
threads access them. This may improve performance when lazy FPSIMD restore
is disabled.
