Failing test prebuilt_cfg/x86/linux/cfg/hello_world with aarch64 build/host

[ekilmer]

In testing on cxx-common repo and LLVM 11, I get the following failure on the aarch64 host:

F0527 14:21:29.388495  3685 InstructionLifter.cpp:558] Check failed: word_size == arg_size Expected integer argument to be machine word size (32 bits) but is is 64 instead in instruction at 8048288

The related amd64 passes without failure (not sure if output is correct, though)

Will update with link to logs and remill,anvill dependencies
