Diego Novillo ef548d2918 SamplePGO - Sort samples by source location when emitting as text. 
When dumping function samples or writing them out as text format, it
helps if the samples are emitted sorted by source location. The sorting
of the maps is a bit slow, so we only do it on demand.

Diego Novillo a7f1e8ef83 Add inline stack streaming to binary sample profiles. 
With this patch we can now read and write inline stacks in sample
profiles to the binary encoded profiles.

In a subsequent patch, I will add a string table to the binary encoding.
Right now function names are emitted as strings every time we find them.
This is too bloated and will produce large files in applications with
lots of inlining.
