This pull request fixes unnecessary overhead introduced by duplicate parsing and typechecking when IR conversion check is enabled. As tested with
bazel run -c opt //xls/modules/zstd:zstd_dec_dslx_testand commented tests for simplicity of measuring IR conversion check overhead - onmainbranch it takes ~3.5 min to finish executing the target, while with this PR changes it finishes in ~38 seconds. Without IR conversion check, the execution time is ~27 seconds. As a result it narrows down IR conversion check overhead from ~3 min to ~11 seconds in the tested case.
