This pass attempts to speculatively use a sqrt instruction if one exists on the target, falling back to a libcall if the target instruction returned NaN. This was enabled for MIPS and System-Z, but is well guarded and is good for most targets - GCC does this for (that I've checked) X86, ARM and AArch64. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@213752 91177308-0d34-0410-b5e6-96231b3b80d8
