The 64-bit MSYS2 job often times out in our CI, though we already have limited it to a very minimum by using --without-default-devices etc. GCC is incredibly slow here. By using Clang instead of GCC, the job is ca. 15 minutes faster - that's enough buffer to avoid the timeouts here.
The caveat is that Clang does not support __attribute__((gcc_struct)) on Windows. So we have to make sure that our structs are still padded right. By checking the build with "pahole", Daniel discovered that there is still an issue in VTD_IR_TableEntry, so that's why this struct gets changed in this patch series, too. All other structs did not show a difference with "pahole", so building with Clang should hopefully be fine after these modifications here. Daniel P.
