[docs] Fixing Sphinx warnings to unclog the buildbot

Lots of blocks had "llvm" or "nasm" syntax types but either weren't following
the syntax, or the syntax has changed (and sphinx hasn't keep up) or the type
doesn't even exist (nasm?).

Other documents had :options: what were invalid. I only removed those that had
warnings, and left the ones that didn't, in order to follow the principle of
least surprise.

This is like this for ages, but the buildbot is now failing on errors. It may
take a while to upgrade the buildbot's sphinx, if that's even possible, but
that shouldn't stop us from getting docs updates (which seem down for quite
a while).

Also, we're not losing any syntax highlight, since when it doesn't parse, it
doesn't colour. Ie. those blocks are not being highlighted anyway.

I'm trying to get all docs in one go, so that it's easy to revert later if we
do fix, or at least easy to know what's to fix.

When `-analyze` is specified, :program:`opt` performs various analyses

in a few cases, it will print output to standard error or generate a file with

program.

 This option causes opt to strip debug information from the module before
 applying other optimizations.  It is essentially the same as :option:`-strip`
 applying other optimizations.  It is essentially the same as `-strip`
 but it ensures that stripping of debug information is done first.
