This patch optimizes the FPSCR update on exception and rounding change
functions by just updating its value if new value if different from
current one.  It also optimizes fedisableexcept and feenableexcept by
removing an unecessary FPSCR read.

This patch fix the missing symbol __fe_nomask_env from commit
41e8926aa4b7f17bc95984737ee82a254ad0911c for GLIBC_2.1.
