This fixes an issue where `PatchEntries` overwrites function body but
keeps CFI untouched. Existing FDEs thus become invalid. This doesn't
affect unwinding because patched functions are transparent from

BAT contains metadata about fragment relationships. Use it directly
before name-based matching. This removes warnings about control flow
between unrelated fragments.

Given that this change increases the size of eh_frame section, should we make
it dependent on `enable-bat`, i.e. when we expect to feed the binary back to
BOLT?
Because otherwise this "fix" is a pure size regression.
