[issue25827] Support ICC in configure

Thank you David for including me in this issue. 

On ICC, when executing the instrumented applications, it will generate dynamic information file that has a unique name and .dyn suffix. From my previous experience with GCC and CLANG PGO patch (issue24915), also the output of the autoconf will have to be included in the final diff.

Regarding the place for adding the '-fp-model strict' flags, I had the same dillema when working on the LTO patch (issue25702), because I needed the flags to be propagated to _all_ compilation and linking phases, and finally decided to add them to the CONFIGURE_CFLAGS, CONFIGURE_CFLAGS_NODIST, CONFIGURE_CPPFLAGS, CONFIGURE_LDFLAGS variables in the Makefile.pre.in file. You can try there also and keep the BASECFLAGS clean .
