George Rimar	de83cbf37e	[ELF] - Never use std::sort. It turns out we should not use the std::sort anymore. r327219 added a new wrapper llvm::sort (D39245). When EXPENSIVE_CHECKS is defined, it shuffles the input container and that helps to find non-deterministic ordering.

[ELF] - Never use std::sort.

It turns out we should not use the std::sort anymore.
r327219 added a new wrapper llvm::sort (D39245).
When EXPENSIVE_CHECKS is defined, it shuffles the
input container and that helps to find non-deterministic
ordering.

Patch changes code to use llvm::sort and std::stable_sort
instead of std::sort

[ELF] Add profile guided section layout

This adds profile guided layout using the Call-Chain Clustering (C³) heuristic
from https://research.fb.com/wp-content/uploads/2017/01/cgo2017-hfsort-final1.pdf .

RFC: [llvm-dev] [RFC] Profile guided section layout
     http://lists.llvm.org/pipermail/llvm-dev/2017-June/114178.html

Pass `--call-graph-ordering-file <file>` to read a call graph profile where each
line has the format:

    <from symbol> <to symbol> <call count>
