You should add a test in test/mjsunit/messages.js (search for 'simd' for an
example.) I noticed there is no test for the message on line above though.

Looks like I probably should not have added this to begin with - changed to
asserts and removed this. 

   T(LocaleMatcher, "Illegal value for localeMatcher:%")                        \
   T(NormalizationForm, "The normalization form should be one of %.")           \
   T(NumberFormatRange, "% argument must be between 0 and 20")                  \
