Subject: [PATCH 1/2] [llvm][Support] Avoid setting minor/subminor/build in
VersionTuple::withMajorReplaced
The expectation of this API is to only change the major version of a
preexisting version tuple. However, it was actually adding 0's which
causes unintended changes in serialization or printing.
Instead, check for the existing of the non-major parts of the tuple.
