Always set DECL_NO_INSTRUMENT_FUNCTION_ENTRY_EXIT correctly
When profiling is disabled force DECL_NO_INSTRUMENT_FUNCTION_ENTRY_EXIT
for each function to one. This information is then preserved
through LTO.
With this patch for LTO builds -pg needs to be set on both the
LTO final link and the original source build, to allow -pg
(or -pg -fentry) to be active for that source file. This allows
to build large projects mostly with -pg, except for a few files,
and still use LTO.
