Merge r11075 from bleeding_edge to 3.8 branch: Revert dynamic frame alignment.

Marking aligned frames with a marker can produce false positives since
an optimized frame spill slot may be mistakenly seen as a marker value.

It also breaks the debugger reproducably: Tested when enabling alignment
for all functions and running the debugger unit tests.
