SLP: Initialize variable to fix bootstrap after r277784.
This initializes the rstmt variable with NULL and adds an assert to
check that a value has been given by one of the if cases before use.
This fixes the bootstrap failure due to -Werror.
Committed under the gcc obvious rule.
gcc/ChangeLog:
* tree-vect-slp.c (vectorize_slp_instance_root_stmt): Initialize rstmt.
