Split scheduling out from emitting, to give each their own
timer.

template, for keeping lists of objects allocated from Recyclers, and some
related utilities.

of after, so that any reallocation it does doesn't get counted for the pass
being timed. This probably doesn't account for a timing discrepancy I was
looking into, but I'm fixing it anyway.

This may break some stuff temporarily, but I want to
avoid the propagation of code that assumes this works.

null terminated name, and the system api's require null terminated
strings anyway.

1) stop using MappedFile.
2) if profitable use the sys::path::MapInFilePages api to
read the file.
3) otherwise fallback to read.
When sys::path::MapInFilePages is implemented, this provides
several benefits:
#1: this avoids fragmenting memory for small files.
#2: this avoids extraneous stat calls when the file size is known.
#3: this only keeps the file descriptor open while reading the
file, not for the duration of the lifetime of the memory
buffer. This fixes a serious clang FD 'leak' problem.
I believe that this will work on a win32 machine, but I don't have
one to test on. I'd appreciate it if someone could check.

not an mmapped file. This more closely matches its requirements and
provides an implicitly null terminated buffer, something this
routine had to emulate itself before.

Added member template "Add" to FoldingSetNodeID that allows "adding" arbitrary
objects to a profile via dispatch to FoldingSetTrait<T>::Profile().
Removed FoldingSetNodeID::AddAPFloat and FoldingSetNodeID::APInt, as their
functionality is now replaced using the above mentioned member template.
