For POWER4..POWER8 we align loops of 5..8 instructions to 32 bytes
(instead of to 16 bytes) because that executes faster. This is no

[AArch64] PR84114: Avoid reassociating FMA
As discussed in the PR, the reassociation phase runs before FMAs are formed
and so can significantly reduce FMA opportunities. Although reassociation
could be switched off, it helps in many cases, so a better alternative is to
only avoid reassociation of floating point additions. This fixes the testcase
and gives 1% speedup on SPECFP2017, fixing the performance regression.

Tighten use of HARD_FRAME_POINTER_REGNUM in alias.c (PR 84538)
RTL code needs to be consistent about whether it uses the stack
pointer, the frame pointer or the argument pointer to access a
given part of the frame. alias.c used this to divide accesses
into three independent areas.
The problem in the PR is that we did this for HARD_FRAME_POINTER_REGNUM
even when the register wasn't being used as a frame pointer. We can't
do that because the frame pointer is then just any old allocatable
register and could certainly point to info accessed through the
argument pointer or stack pointer.
