Merge branch 'no_fminf_fmaxf' into 'master'

Replaced all calls to fminf and fmaxf by macros

As the Intel compiler can't handle these properly, here is a replacement of all calls to `fmaxf` and `fminf` by a macro that just encapsulates the ternary. This produces assembly call to `vmaxpss` and `vminpss` as expected. 

Any reason not to do this ?
