[Qemu-devel] [PULL 02/10] target-mips: remove wrong checks for recip.fmt and rsqrt.fmt

[Leon Alrae <leon.alrae@imgtec.com>]

From: Petar Jovanovic <petar.jovanovic@imgtec.com>

Instructions recip.{s|d} and rsqrt.{s|d} do not require 64-bit FPU neither
they require any particular mode for its FPU. This patch removes the checks
that may break a program that uses these instructions.
