This is currently 16 bytes, the patch reduces it to 4.
(Building with clang on linux x84, I guess others are similar)

The only subfield that might need a bigger type is SymbolPropertySet,
I've moved it to the end of the struct so if it grows, SymbolInfo will
only be 8 bytes.

With a full index of namespace-scope symbols from the LLVM project (200k)
loaded into clangd, this saves ~2MB of RAM.
