[IR] Optimize bitfield layout of Value for MSVC
This should save a pointer of padding from all MSVC Value subclasses.
Recall that MSVC will not pack the following bitfields together:
unsigned Bits : 29;
unsigned Flag1 : 1;
unsigned Flag2 : 1;
unsigned Flag3 : 1;
Add a static_assert because LLVM developers always trip over this
behavior. This regressed in June.
