Documentation tweaks for internal-fn-related optabs
As Bernd requested, this patch adds "This pattern cannot FAIL" to the
documentation of optabs that came to be mapped to interal functions.
For consistency I did the same for optabs that were already being
used for internal functions.
Many of the optabs weren't documented in the first place, so I added
entries for the missing ones. Also, there were some inaccuracies in
the documentation of the rounding optabs. The bitcount optabs said
that operand 0 has mode @var{m} and that operand 1 is under target
control, whereas it should be the other way around.
Tested on x86_64-linux-gnu.

* doc/md.texi (vec_load_lanes@var{m}@var{n}): Document that
the pattern cannot FAIL.

floating-point mode and that all operands have that mode.

floating-point mode, that all operands have that mode, and that
the patterns cannot FAIL. Remove previous documentation referring
to @code{double} and @code{float}.
