[PATCH][AArch64] Purge leftover occurrences of aarch64_nopcrelative_literal_loads

[Kyrill Tkachov]

Hi all,

The patch that renamed all uses of aarch64_nopcrelative_literal_loads into 
aarch64_pcrelative_literal_loads missed out
its extern declaration in aarch64-protos.h and a couple of its uses in 
aarch64.md.
The aarch64_nopcrelative_literal_loads doesn't get initialised anywhere (since 
it's unlinked from the
command-line option handling machinery) so the code that uses it is bogus.

In any case, its use in the aarch64_reload_movcp<GPF_TF:mode><P:mode> and 
aarch64_reload_movcp<VALL:mode><P:mode>
expanders is redundant since they are only ever called through 
aarch64_secondary_reload which gates their use
on !aarch64_pcrelative_literal_loads already. Since these are not standard 
names, their conditions don't actually
matter in any way or checked at any point in the compilation AFAICS.

Bootstrapped and tested on aarch64-none-linux-gnu.

Ok for trunk?

Thanks,
Kyrill
