There are sorts of match pattern for SAT related cases,  there will be
some duplicated code to check the dest, op_0, op_1 are same tree types.
Aka ternary tree type matches.  Thus,  add overloaded types_match func
do this and avoid match code duplication.

The below test suites are passed for this patch:
* The rv64gcv fully regression test.
* The x86 bootstrap test.
* The x86 regression test.
