aarch64: Fix invalid subregs in xorsign [PR118501]
In the testcase, we try to use xorsign on:
(subreg:DF (reg:TI R) 8)
i.e. the highpart of the TI. xorsign wants to take a V2DF
paradoxical subreg of this, which is rightly rejected as a direct
operation. In cases like this, we need to force the highpart into
a fresh register first.
