Do not issue lexing errors found during the parsing of macro body
definitions and parseIdentifier function in AsmParser. This changes the
Parser to not issue a lexing error when we reach an error, but rather
when it is consumed allowing us time to examine and recover from an
error.
As a result, of this, we stop issuing a both lexing error and a parsing
error in floating-literals test. Minor tweak to parseDirectiveRealValue
to favor more meaningful lexing error over less helpful parse error.
