Declare __clear_cache.
...
GCC declares __clear_cache in the gnu modes (-std=gnu++98,
-std=gnu++11), but not in the strict modes (-std=c++98, -std=c++11). This patch
declares it and therefore fixes the build when using one of the strict modes.

AArch64: use __clear_cache under GCCish environments
...
AArch64 is going to need some kind of cache-invalidation in order to
successfully JIT since it has a weak memory-model. This is provided by
a __clear_cache builtin in libgcc, which acts very much like the
32-bit ARM equivalent (on platforms where it exists).

On PowerPC, the cache-flush instructions dcbf and icbi are treated as
...
loads. On FreeBSD, add PROT_READ page protection flag before flushing
cache.

Go ahead and get rid of the old page size interface and convert all the
...
users over to the new one. No sense maintaining this "compatibility"
layer it seems.

This patch adds memory support functions which will later be used to implement section-specific protection handling in MCJIT.
