Description

We should add a timer to TypeAnalysis and ask the user to send a bug report, after the compile time crosses a certain relative threshold.

Contributor guide

Research direction
Study the LLVM Timer class and its usage pattern in the LLVM codebase. Then, integrate a timer into the TypeAnalysis pass to measure compile time. When the time exceeds a relative threshold, prompt the user to submit a bug report.
