c++: Fix error recovery ICE [PR112365]
check_field_decls for DECL_C_BIT_FIELD FIELD_DECLs with error_mark_node
TREE_TYPE continues early and doesn't call check_bitfield_decl which would
either set DECL_BIT_FIELD, or clear DECL_C_BIT_FIELD. So, the following
testcase ICEs after emitting tons of errors, because
SET_DECL_FIELD_CXX_ZERO_WIDTH_BIT_FIELD asserts DECL_BIT_FIELD.
The patch skips that for FIELD_DECLs with error_mark_node, another
option would be to check DECL_BIT_FIELD in addition to DECL_C_BIT_FIELD.
