[AArch64] Use calls for SVE TLSDESC
One (unintended) side effect of the patches to support multiple
ABIs is that we can now represent tlsdesc calls as normal calls
on SVE targets. This is likely to be handled more efficiently than
clobber_high, and for example fixes the long-standing failure in
gcc.target/aarch64/sve/tls_preserve_1.c.
