The backtracking stack (which is actually a generic stack) used to be statically sized. At 10k elements, it was fairly large, but still easy to overflow on large subject strings. This CL changes it to a std::vector-based implementation instead which grows on-demand. Drive-by: Add braces to the BYTECODE cases to make clang-format produce a nicer output.

This removes two default switch cases for unsupported opcodes, and replaces them by explicit lists. This makes it easy to see what is currently not supported in Liftoff. In a follow-up CL, each bailout will be associated with a category to track which features currently cause Liftoff to bailout. This change also makes Liftoff crash (in UNREACHABLE) if invoked with asm.js code. Hence, change the asm.js tests to not test Liftoff. In production, we do not invoke Liftoff for asm.js anyway.

On Android libraries there are zero length entries within the ranged symbols which break our range processing. This updates the logic to only add entries for zero-length entries if they aren't within the range of the previously added entry.

On Android we load the native library directly from the APK. As such, we need to convert symbols from the mapped APK to the underlying .so when symbolizing the ticks. This CL adds a --apk-embedded-library argument to tick processor to enable specifying which unstripped library file was embeded in the APK and enable symbolizing.

Seth Brenith authored
If we need to build an icu::UnicodeString for a string that is currently in one-byte representation, we first have to expand the string's content into a two-byte representation. Doing so involves allocating an array, which is slow. With this change, we can convert short strings on the stack instead to save time. The cutoff length for what counts as "short" is pretty arbitrary, but we believe many strings fit into an 80-column line. This increases the score of cdjs in JetStream 2 by 35% on my machine, because cdjs is basically a test of localeCompare throughput.

This is a quick fix for the recent bailout-on-uninitialized feature of the serializer, which does not work with resumables. For now, simply treat the ResumeGenerator bytecode as if it was an exception handler entry point.
