Merge #21274: assumptions: Assume C++17
5e531e6beb5381c0be5efaa24b7e423e593568e4 assumptions: check C++17 assumption with MSVC (fanquake)
c7b46489f8c4d880382248fb47266d81948bbce0 assumptions: assume a C++17 compiler (fanquake)
Pull request description:
This has been the case since #20413.
This should also enable the check for MSVC. From my reading of https://docs.microsoft.com/en-us/cpp/build/reference/zc-cplusplus?view=msvc-160 and https://devblogs.microsoft.com/cppblog/msvc-now-correctly-reports-__cplusplus/ if we set the `/Zc:__cplusplus` switch in additional options, MSVC will report the correct value for `__cplusplus`. However I have not tested this.
