invoke.texi: Fix some skipping UrlSuffix problem for MIPS

The problem is that, there are these lines in mips.opt.urls:
  ; skipping UrlSuffix for 'mabi=' due to finding no URLs
  ; skipping UrlSuffix for 'mno-flush-func' due to finding no URLs
  ; skipping UrlSuffix for 'mexplicit-relocs' due to finding no URLs

These lines is not fixed by this patch due to that we don't
document these options:
  ; skipping UrlSuffix for 'mlra' due to finding no URLs
  ; skipping UrlSuffix for 'mdebug' due to finding no URLs
  ; skipping UrlSuffix for 'meb' due to finding no URLs
  ; skipping UrlSuffix for 'mel' due to finding no URLs

gcc
	* doc/invoke.texi(MIPS Options): Fix skipping UrlSuffix
	problem of mabi=, mno-flush-func, mexplicit-relocs;
	add missing leading - of mbranch-cost option.
	* config/mips/mips.opt.urls: Regenerate.
