RFR(XXXS): 8205996: JDK-8205906 broke the build on Mac

[Markus Gronlund]

Greetings,

Looks like the check-in for https://bugs.openjdk.java.net/browse/JDK-8205906 broke the product build when running on Mac (builds fine using the "debug" target that I tested before pushing.

There is a P1 filed now to restore the Mach builds, so I would appreciate a quick ok. 

Webrev: http://cr.openjdk.java.net/~mgronlun/8205996/webrev00/ 
Bug: https://bugs.openjdk.java.net/browse/JDK-8205996

Summary: inlining char constants and lengths.

Currently running a verification job in MACH5 (product build)
