    [Interpreter] Increase allowed expression depth for logical test expressions · b38795f3
    Ross McIlroy authored
    Changes the handling of TestResultScopes to allow them to be reused by
    logical tests by rewiring instead of using a new TestResultScope. 
    Also does the following:
     - moves some fields about in TestResultScope to reduce it's size
     - moves RegisterListFreeEvent to the end of ReleaseRegisters to enable
       it to be tail-called.
    
    This increases the allowed depth of logical expressions which the
    compiler can handle without overflowing the stack by about 2x on x64.
