Since there is an extra error code passed to the exception handler,
INCOMING_FRAME_SP_OFFSET is return address plus error code for the
exception handler. This patch updates INCOMING_FRAME_SP_OFFSET to
the correct value for the exception handler.
This patch exposed a bug in DWARF stack frame CFI generation, which
assumes that INCOMING_FRAME_SP_OFFSET is the same for all functions:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81570
It sets and caches the incoming stack frame offset with the same
INCOMING_FRAME_SP_OFFSET for all functions. When there are both
exception handler and normal function in the same input, the wrong
incoming stack frame offset is used for exception handler or normal
function, which leads to
