C: Don't print usage message and quit when called with no arguments,
as this is used for testing C output
OCaml: Fix generation of datatypes with multiple type arguments
OCaml: Generate P_cons pattern correctly
C: Fix constant propagation to not propagate letbindings with type
annotations. This behaviour could cause type errors due to how type
variables are introduced. Now we only propagate letbindings when the
type of the propagated variable is guaranteed to be the same as the
inferred type of the binding.
Tests: Add OCaml tests to the C end-to-end tests (which really
shouldn't be in test/c/ any more, something like test/compile might be
better). Currently some issues with reals there like interpreter.
Tests: Rename list.sail -> list_test.sail because ocaml doesn't want
to compile files called list.ml.

Interpreter used a re-write (vector concat removal) that is dependent
on the vector_string_to_bit_list rewriting pass. This fixes the
interpreter to work without either vector concat removal, or turning
bitstrings into vector literals like [bitzero, bitzero, bitone]. This
has the upside of reducing the number of steps the interpreter needs
for working with bitvectors so should improve interpreter performance.
We also now test all the C compilation tests behave the same using the
interpreter. Currently the real number tests fail due to limitations
of Lem's rational library (this must be fixed in Lem). This required
supporting configuration registers in the interpreter. As such the
interpreter was refactored to more cleanly process registers when
building an initial global state. The functions are also collected
into the global state, which removes the need to search for them in
the AST every time a function call happens. This should not only
improve performance, but also removes the need to pass an AST into the
interpretation functions.

Test the builtin functions by compiling them to C, OCaml, and OCaml
via Lem. Split up some of the longer builtin test programs to avoid
stack overflows when compiling to OCaml, as 3000+ line long blocks can
cause issues with some re-writing steps.
Also test constant-folding with builtins (this should reduce the
asserts in these files to assert true), and also test constant folding
with the C compilation.
Fix a bug whereby vectors with heap-allocated elements were not
initialized correctly.
Fix a bug caused by compiling and optimising empty vector literals.
Fix an OCaml test case that broke due to the ref type being used. Now
uses references to registers.
Fix a bug where Sail would output big integers that lem can't
parse. Checks if integer is between Int32.min_int and Int32.max_int
and if not, use integerOfString to represent the integer. Really this
should be fixed in Lem.
Make the python test runner script the default for testing builtins
and running the C compilation tests in test/run_tests.sh
Add a ocaml_build_dir option that sets a custom build directory for
OCaml. This is needed for running OCaml tests in parallel so the
builds don't clobber one another.
