Given that T is a scalar type, return the IR type that should be used for load and store operations.
For example, this might be i8 for _Bool or i96 for _BitInt(65). The store size of the load/store type (as reported by LLVM's data layout) is always the same as the alloc size of the memory representation type returned by ConvertTypeForMem.
As an optimization, if you already know the scalar value type for T (as would be returned by ConvertType), you can pass it as the second argument so that it does not need to be recomputed in common cases where the value type and load/store type are the same.

ConvertTypeForMem - Convert type T into a llvm::Type.
This differs from ConvertType in that it is used to convert to the memory representation for a type. For example, the scalar representation for _Bool is i1, but the memory representation is usually i8 or i32, depending on the target.
This differs from ConvertType in that it is used to convert to the memory representation for a type. For example, the scalar representation for _Bool is i1, but the memory representation is usually i8 or i32, depending on the target.
We generally assume that the alloc size of this type under the LLVM data layout is the same as the size of the AST type. The alignment does not have to match: Clang should always use explicit alignments and packed structs as necessary to produce the layout it needs. But the size does need to be exactly right or else things like struct layout will break.
