Move ferror out of hot loop of file cache
glibc ferror is surprisingly expensive. Move it out of the hot loop
of finding lines by setting a flag after the actual IO operations.
gcc/ChangeLog:
PR preprocessor/118168
* input.cc (file_cache_slot::m_error): New field.
(file_cache_slot::create): Clear m_error.
(file_cache_slot::file_cache_slot): Clear m_error.
(file_cache_slot::read_data): Set m_error on error.
(file_cache_slot::get_next_line): Use m_error instead of ferror.
