What types of compiler optimizations are comonly used in C++? [closed]

I am trying to get high lever overview of optimizations used in C++ language. According to wikipedia article, compilers use these optimizations:

1. Peephole optimizations
2. Local optimizations
3. Global optimizations
4. Loop optimizations
5. Prescient store optimizations
6. Interprocedural, whole-program or link-time optimization
7. Machine code optimization and object code optimizer

It it completely new topic for me. Till now I was thinking that optimization is only done during compilation. I didn't expect that is also done during linking or even after...

Could you tell me if C++ language supports all of mentioned optimizations?

EDIT: That's right, mentioned wiki article was not language specific, so purpose of that question was to get knowledge if these optimizations are commonly used and supported by C++ compilers.

There is a lot of detailed manuals which describes each compiler flag, but none of them provides general overview similar to mentioned wiki article, which will be C++ specific.
