re PR bootstrap/41031 (ICE in insert_value_copy_on_edge preventing bootstrap on sparc64 and s390x, testcase on cris-elf)

PR tree-optimization/41031
* tree-outof-ssa.c (insert_value_copy_on_edge): Use promote_decl_mode
on the partition variable rather than promote_mode on the source
type. Assert that the partition variable's type has the same
mode as the source value's.
