Array.indexOf accepts an optional fromIndex argument. When non-negative,
this argument restricts the searched indices to those starting at
fromIndex:
[1, 2, 1].indexOf(1,1) == 2
When negative, it is meant to be added to the array length to provide
such initial index for the search:
[1, 2, 1].indexOf(1, -2) == 2
This transformation has been done by the non-optimised builtin but not
by the reducer. The CL adds this construction to the reducer.

The --trace-turbo flag would cause a crash when compiling a WASM_FUNCTION. It
was caused by assuming the OptimizedCompilationInfo had a SharedFunctionInfo
attached if the code isn't a stub and wasm functions are not considered as such.
In order to test this, we've added a new flag to specify were to dump JSON
files: --trace-turbo-path. This is used to make sure we do not leave lots of
files behind in the top-level directory. It should be useful as standalone
feature too.
