ordered correctly.  Previously it would get in trouble when
two patterns were too similar and give them nondet ordering.
We force this by using the record ID order as a fallback.

The testsuite diff is due to alpha patterns being ordered
slightly differently, the change is a semantic noop afaict:

Remove the optimize for code size limitation on r67917. Optimize 64-bit imul by constants into leas + shl regardless if optimizing for code size. The size saving from using imulq isn't worth it. Also, the lea and shl instructions may expose further optimization.

Only perform jump checking if the containing function has no errors,
and add the infrastructure needed to do this.

On the testcase in the PR, we produce:

t.cc:6:3: error: illegal goto into protected scope
  goto later;
  ^
t.cc:7:5: note: jump bypasses variable initialization
  X x;
    ^

Remove this test because it checks wheter optimizer handled @llvm.dbg.global_variable appropriately or not. LLVM does not use this scheme to encode debug info for global variables any more.

Remove test to check bugfix in handing debug info for global variables using intrinsics. Now, debug info for global variable is encoded using metadata. The old code path is now history and there is no need to have a test to check a bug fix in old code path.
