Split IsAnyOf() into log(n) stages, where each stage performs a hashcode
check.
Previously there was a single hash test across the bitwise-or of all the
types being considered. If this passed, then each type would be tested
with Is<T>() individually. With this change, the list of types will be
recursively split into two, which each block hash-code checked. This is
repeated until we reach fewer than 4 types to check, where the test
decays to using Is<T>() for each type.
Also renamed `combined_hashcode` to `full_hashcode`, and used the term
CombinedHash for new helpers that bitwise-or the hashes from a number
of types.

When converting a for-loop to a loop, we were not cloning the for-loop's
body, but rather the statements within it. This worked fine, except if
we also hoisted a variable to a let within that body, which requires the
body to be cloned for the 'insert before' to work. This change clones
the for-loop body, which fixes the problem, but introduces a block in
the destination AST, which is ugly, but not incorrect.

It's too easy to copy diagnostics around and lose track of Source::File
ownership. Ideally we'd place the shared_ptr on the Source, but Sources
are copied _very_ frequently, and we'd lose a huge amount of
performance. Typically, Source::Files are owned externally. The only
time we really need to hold a shared_ptr to these is when a Source::File
is generated by an ICE, as the File points to the C++ source file that
raised the error.

Previously the conversion lost precision because of the repeated
float additions and rounding of float to uint. It is reworked to operate
using only integers, giving a better precision (3e-5 instead of 2e-3)
for all periods between 1ns and 2^16ns (which all GPUs seem to fall in
to).
The QueryHelper test is reworked to test multiple periods to provide
better certainty that the maths in the conversion is correct.

The current directory and namespace collides quite spectacularly with
the google benchmark include directory and namespace.
This becomes very hard to work around when there's a .cc file in src/
that wants to include "benchmark/benchmark.h", as MSVC appears to
resolve this to the relative path, while GCC and Clang resolve to the
compiler specified include directory.

This change adds an override for Transform::ShouldRun() for many of the transforms that can trivially detect whether running would be a no-op or not. Most programs do not require all the transforms to be run, and by skipping those that are not needed, significant performance wins can be had.
This change also removes Transform::Requires() and Program::HasTransformApplied(). This makes little sense now that transforms can be skipped, and the usefulness of this information has been severely reduced since the introduction of transforms that need to be run more than once.
Instread, just document on the transform class what the expectations are.
