[14 regression] Fix insn types in risc-v port

So one of the broad goals we've had over the last few months has been to ensure
that every insn has a scheduling type and that every insn is associated with an
insn reservation in the scheduler.

This avoids some amazingly bad behavior in the scheduler.  I won't go through
the gory details.

I was recently analyzing a code quality regression with dhrystone (ugh!) and
one of the issues was poor scheduling which lengthened the lifetime of a pseudo
and ultimately resulted in needing an additional callee saved register
save/restore.

This was ultimately tracked down incorrect types on a few patterns.  So I did
an audit of all the patterns that had types added/changed as part of this
effort and found a variety of problems, primarily in the various move patterns
and extension patterns.  This is a regression relative to gcc-13.

Naturally the change in types affects scheduling, which in turn changes the
precise code we generate and causes some testsuite fallout.

I considered updating the regexps since the change in the resulting output is
pretty consistent.  But of course the test would still be sensitive to things
like load latency.  So instead I just turned off the 2nd phase scheduler in the
affected tests.

Bootstrapped and regression tested on rv64gc-linux-gnu.
