PR tree-optimization/63464
* gimple.h (gimple_seq_discard): New prototype.
* gimple.c: Include stringpool.h and tree-ssanames.h.
(gimple_seq_discard): New function.
* optabs.h (lshift_cheap_p): New prototype.
* optabs.c (lshift_cheap_p): New function, moved from...

caller.
(optimize_range_tests_xor): Likewise. Fix up comment.
(extract_bit_test_mask, optimize_range_tests_to_bit_test): New
functions.
(optimize_range_tests): Adjust update_range_test caller.
Call optimize_range_tests_to_bit_test.
