libgcc: Export XF, TF, HF and BFmode specific _BitInt symbols from libgcc_s.so.1...

Rainer pointed out that __PFX__ and __FIXPTPFX__ prefix replacement is done
solely for libgcc-std.ver.in and not for the *.ver files in config.
I've used the __PFX__ prefix even in config/i386/libgcc-glibc.ver because it
was used for similar symbols in libgcc-std.ver.in, and that results in those
symbols being STB_LOCAL in libgcc_s.so.1.  Tests still work because gcc by
default uses -static-libgcc when linking (unlike g++ etc.), but would
have failed when using -shared-libgcc (but I see nothing in the testsuite
actually testing with -shared-libgcc, so am not adding tests).

With the patch, libgcc_s.so.1 now exports
__fixtfbitint@@GCC_14.0.0 FUNC GLOBAL DEFAULT
__fixxfbitint@@GCC_14.0.0 FUNC GLOBAL DEFAULT
__floatbitintbf@@GCC_14.0.0 FUNC GLOBAL DEFAULT
__floatbitinthf@@GCC_14.0.0 FUNC GLOBAL DEFAULT
__floatbitinttf@@GCC_14.0.0 FUNC GLOBAL DEFAULT
__floatbitintxf@@GCC_14.0.0 FUNC GLOBAL DEFAULT
on x86_64-linux which it wasn't before.
