Remove all target specific __ieee754_sqrt(f/l) inlines

Browse Source 
Remove the now unused target specific__ieee754_sqrt(f/l) inlines.
Also remove inlines of sqrt which are for really old GCC versions.
Removing these is desirable, under the general principle of leaving
such inlining to the compiler rather than trying to do it in installed
headers, especially when only very old compilers are affected.

Note that removing inlines for __ieee754_sqrt disables inlining in the
sqrt wrapper functions.  Given the sqrt function will typically only be
called for negative arguments, it doesn't matter whether the inlining
happens or not.
