The movsi and movdi constraints allowed the source to be any
absolute symbolic expression ("S").  That's OK for operands that
have already been vetted by the aarch64_mov_operand predicate but
causes problems if the register allocator substitutes an equivalence
(the usual "the constraints can't accept more than the predicates"
restriction).

Although all other uses of "S" in the backend are redundant and could
in principle be removed, "S" itself is a publicly-documented constraint
and so we'd have to keep its definition.  This patch therefore adds a
new "Usa" constraint for legitimate absolute address operands.

TM_MULTILIB_CONFIG is not set in config.gcc when building with multilib
for arm targets, leading to config/arm/t-multilib not including any of
the files (t-aprofile and t-rmprofile) definining the architecture and
FPU to build multilib for. This patch fixes that by setting
TM_MULTILIB_CONFIG to with_multilib_list's value after it has been
checked. It also fix a trailing whitespace issue.

If we decide to allocate a call-clobbered register R to a value that
is live across a call, LRA will create a new spill register TMPR,
insert:

   TMPR <- R

before the call and

   R <- TMPR

after it.  But if we then failed to allocate a register to TMPR, we would
always spill it to the stack, even if R was known to be equivalent to
a constant or to some existing memory location.  And on AArch64, we'd
always fail to allocate such a register for 128-bit Advanced SIMD modes,
since no registers of those modes are call-preserved.

This patch avoids the problem by copying the equivalence information
from the original pseudo to the spill register.  It means that the
code for the testcase is as good with -O2 as it is with -O,
whereas previously the -O code was better.
