Nico Weber 60a32e805a Let TableGen write output only if it changed, instead of doing so in cmake, attempt 2 ... This relands r330742: """ Let TableGen write output only if it changed, instead of doing so in cmake. Removes one subprocess and one temp file from the build for each tablegen invocation. No intended behavior change. """ In particular, if you see rebuilds after this change that you didn't see before this change, that's unintended and it's fine to revert this change again (but let me know). r330742 got reverted because some people reported that llvm-tblgen ran on every build after it. This could happen if the depfile output got deleted without deleting the main .inc output. To fix, make TableGen always write the depfile, but keep writing the main .inc output only if it has changed. This matches what we did in cmake before.
