Some C backend refactoring

Make it so that jib_compile.ml never relies on specific string encodings
for various constructs in C. Previously this happened when
monomorphisation occured for union constructors and fields, i.e.

x.foo -> x.zfoo_bitsz632z7

Now identifiers that can be modified are represented as (id, ctyp list)
tuples, so we can keep the types

x.foo -> x.foo::<bits(32)>

This then enables us to do jib IR -> jib IR rewrites that modify types

In particular there is now a rewrite that removes tuples as an IR->IR
pass rather than doing it ad-hoc in the C code generation, although this
is not on by default

Note that this change seems to have triggered an Ott bug so jib.lem is
now checked in and not generated from Ott
