John Stiles 3ff77f4862 Fix inliner bug discovered by fuzzer. 
Intrinsic-call optimization can be triggered during inlining. In this
case, inlining turned `normalize(x)` into `normalize(constant-value)`.

DSL is used to implement optimizations for a handful of intrinsic calls,
including `normalize`, which internally relies on `length`.

The DSL expects that it can use the IRGenerator to handle function
calls. This was not working because we were finished with the initial
compilation pass, and the IRGenerator's symbol table is removed when
finish() was called.

We now temporarily give a symbol table back to the IRGenerator while
the inliner runs. We remove it again as soon as inlining is complete.
