Relax isPOD rules so ctors don't make structs non-POD
Issue 11503 - immutable return value from pure function implicitly converts to mutable.
Remove CallExp::implicitCastTo altogether.

The pure -> immutable case is checked in implicitConvTo as well,
and since it yields MATCHexact, the castTo() in
Expression::implicitCastTo is a no-op anyway.
Issue 11909 - Struct members and static arrays break pure function escape analysis (immutability violation).
Clarify traverseIndirections implementation.

No functional change intended.
Make traverseIndirections() return bool instead of int.

fix Issue 12010 - Undefined template symbols for static library linked with debug symbols

Struct destructors and postblits will be stored in TypeInfo. So, partial semantic3 running for structs declared in non-root modules should also consider them.
