[PATCH] [lld] Teach LLD how to parse complete linker scripts

[Rafael Auler]

Hi Sean, thanks for your input, I didn't know your write-up about linker scripts, it's great!

I'll check the dumped scripts for correct behavior. I put in a comment the reference I used to implement the parser (see LinkerScript.h:692); it's the GNU manual, e.g. https://sourceware.org/binutils/docs/ld/SECTIONS.html#SECTIONS. 

I'll work on your suggestions.
