Ecma262: Separate subsections for mathematical functions in Algorithm Conventions

[siriniok]

There is a lot of references to mathematical functions like min, max, abs, etc. in the specification. All of them now described in the end of section 5.2 Algorithm Conventions. And it's impossible to reference any of these functions directly, so links to them currently lead to the section 5.2. It's enough confusing.
I think we need to create a separate subsection for each mathematical function. It will make much simpler to find them and understand what they do.

I think instead of creating artificial sections we should just make the links go directly to the definitions.

There are now direct links to the various mathematical operations (and the date ops too). which should make it much easier to find them. Thanks for the feedback @siriniok and sorry for the long delay :)
