Rather than making the interner be a global lazy_static mutex, put it in
a thread-local RefCell. This doesn't change anything in terms of
sharing (since we're currently actually just single threaded), but
avoids the overhead of a mutex, for a nice performance boost (compared
to the mutex version):
hello outpath time: [726.71 ms 729.79 ms 735.69 ms]
change: [-5.7277% -3.9733% -2.1144%] (p = 0.00 < 0.05)
Performance has improved.

This is the most naive version of string interning possible - we store a
map from the string itself to the pointer behind a global mutex, and
memoize the allocation of all strings below a threshold length (16
bytes, for now) into that map. This requires leaking /all/ strings,
since it's not easy to know just from the pointer that a string has been
interned - so interning is disabled if string leaking is also disabled.
In the case where we're leaking strings (the default), even the naive
version of this gets us a pretty nice perfomance boost:
hello outpath time: [742.54 ms 745.89 ms 749.14 ms]
change: [-2.8722% -2.0135% -1.0654%] (p = 0.00 < 0.05)
Performance has improved.
However, in the case where we're not leaking strings, we have to keep
track of which strings have and haven't been interned, which makes this
a little worse:
hello outpath time: [779.30 ms 792.82 ms 808.74 ms]
change: [+2.5258% +4.0884% +5.8931%] (p = 0.00 < 0.05)
Performance has regressed.
Hopefully we can close the gap here a bit with some clever
tricks (coming next).

It turns out the pg_format thing is just too slow for my use-cases
most of the time, even when pooling the mf. Most queries stay 90%+ in
the perl script, even though they are very fast to execute on their
own, screwing up the traces a lot.
So instead I replace the `postgres-simple` quasi-quoter that strips
whitespace (and tends to screw up queries anyway) with a simple one
that just removes the outer indentation up to the first line.
Why did I spend so much time on pg_format haha

Default to always leaking strings, and copying strings by copying
pointers rather than cloning the underlying allocation. This (somewhat
bafflingly) doesn't seem to affect any benchmarks, but paves the way for
some tricks around string allocation that do.
Unfortunately, we can't do this (yet?) for contextful strings, for
reasons I don't currently understand but which I will address later,
when I address contextful strings more holistically.
I've left a flag in here to disable this, both to test the cloning logic
for strings for when/if we decide to bring this back, and to allow
people who care more about memory usage than perf to disable leaking.

Previously, OpConstant would display some detail about its
ConstantIdx: whether it's a thunk or closure, and what its address
is. This has been expanded to also show when the ConstantIdx is a
blueprint, along with the blueprint's address, and to the other
opcodes that use a ConstantIdx.
Currently, it seems like blueprint addresses don't correspond to the
address of the thunk listed in the bytecode output, but it's still
useful to see that the constant being grabbed is a blueprint, and
maybe this pointer can be made to make more sense in the future.

path_exists was returning an error when certain common IO errors were

an error because the underlying call to Path::try_exists threw an
error because null isn't a directory. But if null isn't a directory,
then the path is invalid, so this should really be returning
false. That's what nix's behavior is and that's what makes sense.
