> Nystrom alias issue: OMPM2001 assert "the child mp pu pool is not equal to
> _memPool"
>
> This assert happens because,
> in AliasAnalyzer::~AliasAnalyzer, assume lower_mp will always copy parent
> PU's aliasTagMap to child in Transfer_Maps.
> This is correct for APO because lower_mp happens after LNO, then alias
> analyzer is already there.
>
> for openmp testcase, lower_mp is invoked before LNO and preopt in
> Backend_Processing,
> so the child PU doesn't have aliasTagmap copied from parent PU.
> previous fix for APO is not good, it copies extra map and delete directly.
>
>
> Now the fix is always not copy alias tag map when lower_mp create parallel
> PU.
> 1. In lower_mp, Create_MicroTask, mark don't copy alias tag map if
> aliasanalyzer exist.
> 2. In AliasAnalyzer::~AliasAnalyzer, remove code for deleteing child PU's
> aliastagmap.
