SjLjEHPrepare and WasmEHPrepare directly emit calls to these by
name, and these are not tracked in RuntimeLibcalls. It will be easier
to fix this when RuntimeLibcalls is turned into an analysis, so just
add the entries for now.

Subject: [PATCH] RuntimeLibcalls: Add entries for some exception related
functions
SjLjEHPrepare and WasmEHPrepare directly emit calls to these by
name, and these are not tracked in RuntimeLibcalls. It will be easier
to fix this when RuntimeLibcalls is turned into an analysis, so just
add the entries for now.
