Detailed Description

Extension point for target-specific MCExpr subclasses with a relocation specifier, serving as a replacement for MCSymbolRefExpr::VariantKind.

Limit this to top-level use, avoiding its inclusion as a subexpression.

NOTE: All subclasses are required to have trivial destructors because MCExprs are bump pointer allocated and not destructed.
