f212ec0263 Add a trivial dead code elimination transform. 
Its purpose is to sweep up basic blocks with no predecessors,
which are annoying to handle explicitly elsewhere.

47cbadb564 Revert "Ensure bindings are created in correct order for e.g. "x, y = y, x"." 
This reverts commit bcd1832203.

The bindings are actually created in lexical order, as evident
in e.g. "x = lambda: x". The safety provided by this check should
be instead provided by a local access analysis.

bfabca494b Remove regions from types. 
Unification-based inference for regions is useful with a language
that has let bindings (which would propagate the regions) and
functions polymorphic over regions. For reasons of simplicity,
ARTIQ has neither, and making unification-based inference work would
essentially mean adding region coercions between most AST nodes,
and having every source subexpression have its own region variable,
with the appropriate subtyping relationship.

It's simpler to just keep that state outside of typedtree.

6bf95397d7 Rename package py2llvm to compiler. 
Since the package implements a typechecker along with a code generator,
and the typechecker will be run before or together with transformations,
this name is more descriptive.
