Fix syntaxError on lambda inside decltype (#4650) 
Use case where it gave an issue:

using customComparator = decltype([] (const X& lhs, const X& rhs) { return lhs.CompareTo(rhs); });
std::map<X, int, costomComparator> m;

greatly sped up `dmake` (#4630) 
* dmake.cpp: use `endsWith()` in `getCppFiles()`

* dmake.cpp: optimized string concatenation in `getDeps()`

* dmake.cpp: avoid duplicated `std::string::find()` in `getDeps()`

* dmake.cpp: no need to get dependencies of headers without `.h` extension in `getDeps()`

* dmake.cpp: do not try to look for file in `externals` folder which does not contain any headers in `getDeps()`

Fix #11401 nullpointer dereference with alignof (#4601) 
* checknullpointer: Don't report dereference with alignof

* Refactor unevaluating operator check in checknullpointer

Unifying these ensures the different checks treat the operators the
same.

* Fix FP with _Alignof and null pointer

Just like alignof, _Alignof does not evaluate its operand.

* CheckNullPointer: Also support compiler specific alignof

This fixes #11401 which is about __alignof__. For good measure, also add
the microsoft extensions __alignof and _alignof.
