Last b4b identical version for IPD build of FV3v0+CCPP

Ongoing development work lead to differences in the results that break bit-for-bit tests with the IPD-build of FV3v0+CCPP, even though the CCPP-build is still correct. This is presumably caused by different compiler optimizations taken once the non-CCPP-compliant physics were removed, because none of the code changes would affect the IPD-build only. This tag saves the last bit-for-bit identical version of the IPD build for future reference.
