[doc] extend.texi copy-editing, 6/N (various coding standards fixes)

- Subject: [doc] extend.texi copy-editing, 6/N (various coding standards fixes)
I've committed another installment of my copy-edits to extend.texi. For this patch, I went through the table at
http://gcc.gnu.org/codingconventions.html#Spelling
and tried to check off everything I haven't already addressed by prior patches in this series. I also took care of a few of the listed markup issues that I could easily check for with search-and-replace.

* doc/extend.texi: Various copy-edits to comply with GCC coding
standards for spelling, terminology, and markup, including use of
American spelling, correct use of terms like "back end" and
"run time", use correct name for GCC, use "@:" markup.
