fix Issue 8081 - pure nothrow unittest problem in generated 'header' file
fix Issue 10002 - calling std.algorithm.remove is impure
fix Issue 10003 - void* UFCS regression
Add new Target hook to retrieve member field alignment.
Remove undefined behavior from test23.

The code tried to load 4 bytes from an 1-3 byte allocation.
LLVM's optimizer actually detects this, marking the entire
result undefined.
[Refactoring] Add hasIdentityOpEquals
[Refactoring] Improve __xopEquals implementation

`ref` parameter is same as a pointer in assembler level, so
storing function pointer of `bool __xopEquals(ref const S, ref const S)` to `bool function(const void*, const void*)` is valid.
Improve hasIdentityOpEquals and fix test result of issue 9694.

TypeInfo.equals should throw an Error if the struct doesn't have const objects equality. For example when the struct has only mutable objects equality.
fix ldiv for shared libraries
fix Issue 3789 - Structs members that require non-bitwise comparison not correctly compared

Additionally fix interpret3.d tests, because class object equality is currently not yet supported in CTFE.
