5817978388 Make new.cc only compile once 
Each test was compiling new.cc for every go.  This optimises that to
just compile it once.

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.

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?).

95c23b1a00 Add the const parameter checker. 
This complains if a non-const parameter is not modified. In the PALs,
the size parameter is modified only by some implementations, so we can
make it const in the ones where it isn't.

49ece8f4e1 Enable the static analyser from clang-tidy. 
Fix a false positive.  The loops in the pagemap accessor are too
complicated for the static analyser to check, so it doesn't spot that a
non-null return is impossible.

d06e539732 Add more checks. 
Add missing parentheses in UNUSED (shouldn't matter, but keeps a checker
that may catch real bugs elsewhere happy).

b5bc09ced3 Add some more checkers. 
Change the result of `operator=` on `Mod` to return `Mod&`.  In this
example:

```c++
Mod<4, int> a;
int b = (a = 8);
```

The value of `b` will now be 0, not 8, and will equal the value of `a`.
Hopefully this is less confusing to users of this class.

c3c71afa57 Move pagemap to using InvalidPointer. 
Replace a constant `uintptr_t` value of 1 that was repeatedly cast to a
pointer with an `InvalidPointer<1>`.

28fac4d700 Fix the remaining clang-tidy warnings. 
This introduces a new `address_t` type and two new casts: `pointer_cast`
and `address_cast` for casting between an `address_t` and a pointer.
These should make it easier to audit the codebase for casts between
pointers and integers.  In particular, the remaining `reinterpret_cast`s
and `pointer_cast`s should be the only places where we could perform
invalid pointer arithmetic.

Also adds a `pointer_offset` helper that adds an offset (in bytes) to a
pointer, preserving its original type.  This is a sufficiently common
pattern that it seemed worthwhile to centralise it.
