I decided to do some testing around the cost of copying vs
decompressing and moved all the drivers in SbsaQemu into the
uncompressed section (as described in
https://github.com/tianocore/tianocore.github.io/wiki/ArmPkg-Compression),
but firmware built with CLANGDWARF causes an alignment fault when
writing the last 64 bytes in __memcpy via FvReadFile ->
AllocateCopyPool -> InternalAllocateCopyPool -> InternalMemCopyMem ->
__memcpy (AArch64/CopyMem.S in BaseMemoryLibOptDxe).
I can confirm that managed to reproduce failure. Sorry, but that's all I
can say at the moment. No idea what is going on here.
