stage2: fix a couple off by one errors
All stage2 tests are passing again in this branch.
Remaining checklist for this branch:
* get the rest of the zig fmt test cases passing
- re-enable the translate-c test case that is blocking on this
* implement the 2 `@panic(TODO)`'s in parse.zig
* use fn_proto not fn_decl for extern function declarations3 files changed, 12 insertions(+), 6 deletions(-)
