compiler: check backend alignment for memequalNN functions
The code was assuming the usual required alignment for the memequalNN
functions (16 bits for int16, 32 for int32, etc.). However, on m68k
the required alignment of int32 is only 16 bits. Assuming the
memequalNN alignment caused the compiler to incorrectly decide that
int32 required a specially generated function rather than calling
memequal32. This then crashed if the type descriptor were generated
after type-specific functions had been written.
Fixes GCC PR 80128.

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.

Use more conservative fences on RISC-V
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
userspace fences because there's no way to know if userspace is touching
memory-mapped I/O regions at compile time.
This will have no impact on existing microarchitecutres because they
treat all fences conservatively.

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.
