RFR: JDK-8240964: Compilation error thrown when long literal used with yield

[Jan Lahoda]

Hi,

The code that detects whether "yield" is a keyword for the yield 
statement or not is accidentally not handling long literals properly, 
and decides "yield 0L;" is not a yield statement, which leads to an 
improper compile-time error. The proposed patch is to simply handle the 
long literals properly.

Proposed patch:

JBS: https://bugs.openjdk.java.net/browse/JDK-8240964

How does this look?

Thanks,
     Jan
