1afd56e964 Fix issue 8785: ValueFlow: Track pointer alias 
This fixes the issue by making `ProgramMemory` keep track of values based on the conditions.

It also removes the `deadpointer` check since it duplicates the `invalidLifetime` check.

5c172bb55a Fix issue 8897: Huge array initializations (#2135) 
* Fix issue 8897: Huge array initializations

iscpp11init would take a lot of time when parsing huge arrays.
This patch add memoization to keeps track that we are parsing an array,
and allows to propagate the result without re-parsing the array for each
of its members.

* Use enum class instead of enum

d918f76a0d Remove useless check introduced by 717aa826d8c98dab533b7c2166eb412b1422b14d (#2130) 
I was confused by the naming in the forum entry (this/that). This would
be a pointer, there's no point checking for it there.

d122b1c722 Fix issue with __declspec and final (#2107) 
* Add missing Qt macros

Add two Qt macros that were missing

* Fix issue with __declspec and final

This change is a bit naive but it fixes the issues I was having when combining __declspec(dllexport) and final classes. Without the fix I get errors along the line of "The code 'class x final :' is not handled. You can use -I or --include to add handling of this code. "

fd3cb24973 leakNoReturnVar: Don't break early (#2095) 
There seems to be no reason for stopping checking the scope if a call to
free() is seen (or fclose() or realloc()), so just continue checking.
Also, if there are multiple arguments, check all, perhaps there are more
memory leaks to warn about.
