8f518c6b05 compiler: Allow None in type hints
Similar to how Python itself interprets None as type(None),
make it translate to TNone in ARTIQ compiler type hints.

594ff45750 compiler: Revert support for None as TNone
This was mistakenly included in fb2b634c4a, and broke the test
case verifying that using None as an ARTIQ type annotation in fact
generates an error message.

fb2b634c4a compiler, language: Implement @kernel_from_string
With support for polymorphism (or type erasure on pointers to
member functions) being absent in the ARTIQ compiler, code
generation is vital to be able to implement abstractions that
work with user-provided lists/trees of objects with uniform
interfaces (e.g. a common base class, or duck typing), but
different concrete types.

@kernel_from_string has been in production use for exactly
this use case in Oxford for the better part of a year now
(various places in ndscan).

GitHub: Fixes #1089.

5d7f22ffa4 compiler: Remove provision for unused four-parameter llptr_to_var() form [nfc]
`var_type` was presumably intended to convert to a target type,
but wasn't actually acted on in the function body (nor was it
used anywhere in the codebase).

d6eb2b023a compiler: monomorphize casts first, but more carefully.
This reverts 425cd7851, which broke the use of casts to define
integer width.

Instead of it, two steps are taken:
  * First, literals are monomorphized, leading to predictable result.
  * Second, casts are monomorphized, in a top-bottom way. I.e.
    consider the expression `int64(round(x))`. If round() was visited
    first, the intermediate precision would be 32-bit, which is
    clearly undesirable. Therefore, contextual rules should take
    priority over non-contextual ones.

Fixes #1252.

49682d0159 Improve Python 3.7 compatibility.
async is now a full (non-contextual) keyword.

There are two more instances:
   - artiq/frontend/artiq_client.py
   - artiq/devices/thorlabs_tcube/driver.py

It is not immediately clear how to fix those, so they are left for
later work.

6e77f65d50 compiler: Clarify recv_rpc value names and documentation [nfc]
Previously, the phi emitted for the pointer parameter to recv_rpc was –
rather confusingly – called "size", and the pseudo-code in the comment
had bit-rotted.

5a79fcf9ba embedding: reimplement 373578bc properly.
The core of the problem that 373578bc was attempting to solve is
that diagnostics sometimes should be chained; one way of chaining
is the loc.expanded_from feature, which handles macro-like expansion,
but another is providing context.

Before this commit, context was provided using an ad-hoc override
of a diagnostic engine, which did not work in cases where diagnostic
engine was not threaded through the call stack. This commit uses
the newly added pythonparser context feature to elegantly handle
the problem.

8a908a7656 llvm_ir_generator: do not use 'coldcc' calling convention.
First, this calling convention doesn't actually exist in OR1K
and trying to use it in Asserts build causes an UNREACHABLE.

Second, I tried to introduce it and it does not appear to produce
any measurable benefit: not only OR1K has a ton of CSRs but also
it is quite hard, if not realistically impossible, to produce
the kind of register pressure that would be relieved by sparing
a few more CSRs for our exception raising function calls, since
temporaries don't have to be preserved before a noreturn call
and spilling over ten registers across an exceptional edge
is not something that the code we care about would do.

Third, it produces measurable drawbacks: it inflates code size
of check:* functions by adding spills. Of course, this could be
alleviated by making __artiq_raise coldcc as well, but what's
the point anyway?

1d8b0d46bc compiler: mark FFI functions as ModRef=Ref using TBAA metadata.
Fascinatingly, the fact that you can mark call instructions with
!tbaa metadata is completely undocumented. Regardless, it is true:
a !tbaa metadata for an "immutable" type will cause
AliasAnalysis::getModRefBehavior to return OnlyReadsMemory for that
call site.

Don't bother marking loads with TBAA yet since we already place
!load.invariant on them (which is as good as the TBAA "immutable"
flag) and after that we're limited by lack of !nonnull anyway.

Also, add TBAA analysis passes in our pipeline to actually engage it.
