Matthew Parkinson 7a198cbda5 Aggressively optimise fast path for allocation 
This change introduces a per small sizeclass free list.  That can be
used to access the free objects for that sizeclass with minimal
calculations being required.

It changes to a partial bump ptr.  We bump allocate a whole OS
page worth of objects at a go, so we don't switch as frequently
between bump and free list allocation.

The code for the fast paths has been restructured to minimise the
work required on the common case, and also it is all inlined for the
common case.

Allocating a zero sized object is moved off the fast path.  Ask for 1
byte if you want to be fast.

Matthew Parkinson 7a8eaec2cc Made a sizecass_t to wrap the sizeclass 
This is useful as codegen is nicer if we use size_t, but the semantics
is uint8_t, and is stored as that in many places in the metadata.
Ultimately should introduce a wrapper to check this invariant.

This massively improves the TLS access at the expense of not being

Matthew Parkinson a8dd065fd7 A few checks for easy corruptions 
Will detect corruption caused by either
* Use-after-free
* Double-free
Neither is comprehensive.  Full temporal safety is not possible.
This just aids with debugging.

David Chisnall d259a87d03 Make clang-tidy fail when it ought to. 
clang-tidy exits with an error code of 0 if the code compiles, even if
there are warnings.  Make it generate a file with the errors and fail
the test if this file exists.

Also remove the -fix flag - we don't want clang-tidy to fix things in CI
(yet?).
