  Log Message:
  -----------
  [IR] Prevent implicit SymbolTableListTraits template instantiation (#111600)

The `SymbolTableListTraits` template is explicitly instantiated for the
following types:
  * `llvm/lib/IR/Function.cpp`
    - `BasicBlock`
  * `llvm/lib/IR/Module.cpp`
    - `Function`
    - `GlobalAlias`
    - `GlobalIFunc`
    - `GlobalVariable`

When LLVM is built on Windows with the `LLVM_EXPORT_SYMBOLS_FOR_PLUGINS`
option enabled, the implicit instantiation of the template prevents the
`SymbolTableListTraits` template from being exported. This causes link
errors when the template or IR API is used in a plugin.

This change prevents the template being implicitly instantiated for
these types.
