Yury Khrustalev 82944350ad malloc: aarch64: Add ifuncs for malloc functions ...

Introduce ifuncs and resolvers for functions pertinent to the
malloc interface on the AArch64 target: malloc, calloc, free,
realloc, memalign, valloc, pvalloc, posix_memalign, aligned_alloc,
free_sized, free_aligned_sized, malloc_usable_size.

A target can define the USE_MULTIARCH_MALLOC macro. In this case
it must provide alternative aliases for the malloc functions that
point to the ifuncs.

This implementation respects the --disable-multi-arch configure
flag. If multi-arch support is disabled, the generic aliases
are used on aarch64.

This patch contains aarch64-specific resolvers. At this point they
return core implementations but in the future they can be changed
to support for features, e.g. to handle memory tagging.
