Fix crash when checking symbol encoding
[Bug #20245]
We sometimes pass in a fake string to sym_check_asciionly. This can crash
if sym_check_asciionly raises because it creates a CFP with the fake
string as the receiver which will crash if GC tries to mark the CFP.
For example, the following script crashes:
GC.stress = true
Object.const_defined?("\xC3")
