Detailed Description

This represents an "assembler immediate".

In its most general form, this can hold ":Kind:(SymbolA - SymbolB + imm64)". Not all targets supports relocations of this general form, but we need to represent this anyway.

In general both SymbolA and SymbolB will also have a modifier analogous to the top-level Kind. Current targets are not expected to make use of both though. The choice comes down to whether relocation modifiers apply to the closest symbol or the whole expression.

Note that this class must remain a simple POD value class, because we need it to live in unions etc.
