Vyacheslav Egorov 04cc5098ab [vm] Enable test pattern (a&b == 0) fusion in AOT on X64/ARM64 ...

Previously we would only fuse this pattern for Smi operations
which (almost) never happens in AOT. This CL enables fusion
for Int64 operations as well.

The implementation is limited to X64 and ARM64 for now
because implementing it on 32-bit platforms is somewhat
cumbersome.
