* symfile.c (symbol_file_add): Move reinit_frame_cache call to 

the callers of symbol_file_add. Gets rid of heuristic fence-post
	warnings on mips and alpha targets when the PC resides in a shared
	library which is not yet read in.
	* coff-solib.c (coff_solib_add), cxux-nat.c (add_shared_symbol_files),
	irix5-nat.c (solib_add), osfsolib.c (solib_add),
	remote-vx.c (vx_open), solib.c (solib_add):
	Add call to reinit_frame_cache after all shared libraries are read in.
	* remote-udi.c (udi_load), remote-vx.c (vx_load_command),
	symfile.c (symbol_file_command, add_symbol_file_command):
	Add call to reinit_frame_cache after symbol_file_add.

But we are stopped in the runtime loader and we do not have symbols
for the runtime loader. So heuristic_proc_start will be called
and will put out an annoying warning.
