For describing section/symbol names we can use unique suffixes,
- Name: '.foo ` - Name: '.foo `
It can be a problem (see https://reviews.llvm.org/D79984#inline-734829),
because  are sometimes used to describe a macros:
- Name: "[[a0]]"
Seems the better approach is to use something else, like "()" or "<>".
This patch does it and refactors the code related.
