RISC-V: Don't prefer FP_REGS for integers
On RISC-V we can't store integers in floating-point registers as this is
forbidden by the ISA. We've always disallowed this, but we were
setting the preferred mode to FP_REGS for some integer modes. This
caused the LRA to blow up with some hard to read error messages.
This patch removes the prefered mode hook, as the right thing to do here
is nothing.

The RISC-V memory model is still in the process of being formally
specified, so for now we're going to be safe and add the I/O bits to

stabilize store merging
Don't let pointer randomization change the order in which we process
store chains. This may cause SSA_NAMEs to be released in different
order, and if they're reused later, they may cause differences in SSA
partitioning, leading to differences in expand, and ultimately to
different code.
bootstrap-debug-lean (-fcompare-debug) on i686-linux-gnu has failed in
haifa-sched.c since r245196 exposed the latent ordering problem in
store merging. In this case, the IR differences (different SSA names
selected for copies in out-of-SSA, resulting in some off-by-one
differences in pseudos) were not significant enough to be visible in
the compiler output.
