2d4f043aae [stringrefs][test] Speed up stringrefs-exec test 
By about 10x-20x depending on platform and configuration.
Shorter test strings make the set of all possible substrings
considerably smaller.

0257b0a3d4 [stringrefs] Fix WTF-8 rejection of surrogate pairs 
Quite embarassingly, the test that the WTF-8 decoder rejects surrogate
pairs was broken: the trailing surrogate was invalid.  (The range of the
second byte for leading surrogates is [A0,AF], and for trailing is
[B0,BF]).  Of course the actual functionality was broken, because the
code that detected surrogate pairs called IsSurrogatePair with swapped
arguments.

cf8fc47445 [stringrefs] Add wtf8_policy immediate to string.new_wtf8 
Following change in https://github.com/WebAssembly/stringref/pull/22.
This adds two new parsing modes: a strict UTF-8 parsing mode, and a
sloppy mode that should replace invalid subsequences with U+FFFD.

7c74a9caea [wasm][test] Represent constant expressions with bytes 
Maintaining an AST class just for testing constant exressions does not
seem justified. This CL changes constant expressions in mjsunit tests
to be represented with bytes, like regular expressions.
