72de33a4 - MC: Add MCAsmInfo::evaluateAsRelocatableImpl and replace VEMCExpr with MCSpecifierExpr

MC: Add MCAsmInfo::evaluateAsRelocatableImpl and replace VEMCExpr with MCSpecifierExpr Expressions with specifier can only be folded during relocation generatin. At parse time the `MCAssembler *` argument might be null, and targets should not rely on the evaluateAsRelocatable result. Therefore, we can move evaluateAsRelocatableImpl from MCSpecifierExpr to MCAsmInfo, so that targets do not need to inherit from MCSpecifierExpr.
