Jon Ross-Perkins 38538ff97f Start handling stack depth issues in explorer (#2799)
Adds stack space handling similar to Clang's approach, but with more support for forwarding return values. Refactors ParseAndExecute for better sharing, and for centralization of the InitStackSpace handling.

Fixes #2795
