[MC] evaluateAsAbsolute requires MCValue::RefKind==0
In `.equ a, 3; .if a@plt`, a@plt does not evaluate to an absolute value
(MCExpr::evaluateAsRelocatableImpl disables evaluation when the Kind !=
0 at parse time). Similarly, when using MCTargetValue,
evaluateAsAbsolute should return false when MCValue::RefKind==0.
This allows us to remove `if (!Asm)` check from MipsMCExpr.cpp
(%hi(0xdeadbeef) is not evaluated to a constant without RefKind) and
make targets less error-prone.
