[PATCH] Fix pow simplification when fabs and sqrt are unavailable

[Kuperstein, Michael M]

Hi,

This adds a missing TLI check for the pow(x, 0.5) -> fabs(sqrt(x)) simplification.

There's a similar problem with exp2, but I don't see a LibFunc::ldexp I can check for.
Anyone has any idea if it's missing on purpose, or just an omission?

Michael
