[MC/AsmParser] Avoid setting MCSymbol.IsUsed in some cases
Avoid marking some MCSymbols as used in MC/AsmParser.cpp when no uses
exist. This fixes a bug in parseAssignmentExpression() which
inadvertently sets IsUsed, thereby triggering:
"invalid re-assignment of non-absolute variable"
on otherwise valid code. No other functionality change intended.
The original version of this patch touched many calls to MCSymbol
accessors. On rafael's advice, I have stripped this patch down a bit.
As a follow-up, I intend to find the call sites which intentionally set
IsUsed and force them to do so explicitly.
