Description

Doesn't fail on yield as parameter in sloppy mode. Does fail for strict mode, but the error message
in strict mode seems to be out of context.

Steps to reproduce
esprima.parse('var obj = { *g(yield) {} };') 
Expected output

Should throw an error

Actual output

Parses invalid program
