Vectorize fast path of _cpp_clean_line.
* configure.ac (AC_C_BIGENDIAN, AC_TYPE_UINTPTR_T): New tests.
(ssize_t): Check via AC_TYPE_SSIZE_T instead of AC_CHECK_TYPE.
(ptrdiff_t): Check via AC_CHECK_TYPE.
* config.in, configure: Rebuild.
* system.h: Include stdint.h, if available.
* lex.c (WORDS_BIGENDIAN): Provide default.
(acc_char_mask_misalign, acc_char_replicate, acc_char_cmp,
acc_char_index, search_line_acc_char, repl_chars, search_line_mmx,
search_line_sse2, search_line_sse42, init_vectorized_lexer,
search_line_fast): New.
(_cpp_clean_line): Use search_line_fast. Restructure the fast
loop to make it clear when we're leaving the loop. Stay in the
fast loop for non-trigraph '?'.
