As part of the effort to refactor old error handling code that
would directly call exit(1), in this patch we change the
interface to `BinaryFunctionPass` to return an Error on
`runOnFunctions()`. This gives passes the ability to report a
serious problem to the caller (RewriteInstance class), so the
caller may decide how to best handle the exceptional situation.

Test Plan: NFC
This patch adds the huge pages support (-hugify) for PIE/no-PIE
binaries. Also returned functionality to support the kernels < 5.10
where there is a problem in a dynamic loader with the alignment of
pages addresses.
