With FLAG_preparser_scope_analysis enabled we now always track unresolved variables in the preparser. Fix the logic for deciding on the correct RCS tracing category to be based on what the preparser does.

These two builtins are a special case in that their calling convention must be kept in-sync since they are both generated from Generate_CallOrConstructVarargs. ConstructVarargs in particular used all available registers. In order to free ebx, the calling convention is changed to pass the last argument on the stack. As part of this change, the order of the last two arguments is swapped since the stack parameter must be tagged.

This fixes a crash with a predicate used during stack unwinding of WebAssembly frames during exception handling. The predicate caused an observable side-effect in JavaScript during unwinding, code that is inherently unhandlified and is not allowed to be observable. The fix actually just removes the entire predicate. This is because the updated proposal causes all JavaScript exceptions to participate in WebAssembly exception handling, allowing modelling of "finally" language constructs to perform cleanup independent of the embedders exception details.

In the logic to run tests on Android, the path is currently relative. This only works when V8 is standalone. When V8 is checkout in another project, the path is wrong. The build_with_chromium check only helps with Chromium, but there are other V8 embedders.

The spec specifies that search and standard can not be valid values for the collation extension keyword. Instead users are expected to use the options bag to set the correct usage options. But, ICU expects the usage option to be set through the collation extension value. In this patch, we set the usage option using the collation extension value in ICU. For resolvedOptions, we filter out this extension value using ICU to be spec compatible. Previously, we stored the usage option on the JSCollator instance. But this patch changes the logic to just look it up from the icu::Collator when required. This saves one word of memory. This fails a test262 that was incorrectly fixed. A follow on patch will fix the test262 test.
