This combines Map::DoneInobjectSlackTracking and Map::ConstructionCount into one more generic 4-bit counter. Counter values from 15 down to 8 are used for in-object slack tracking, values from 7 down to 0 are free to be used for a new counter when in-object slack tracking is inactive.

These methods for used for compressed libraries, where GetSource* functions contained the compressed sources and [GS]etRawSource* the uncompressed sources. This is dead code since the API no longer supports compression. (If you need/want compressed sources, use the external startup data and compress/uncompress on the Embedder's side.)

This patch introduces a new inline runtime function, %_HasFastPackedElements(), and uses it both in the implementation of the 'in' operator and in the array builtins to speed up testing for the existence of an index in an array. In testing with the microbenchmark on the attached bug, for example, the runtime goes from 326ms to 66ms. A reviewer might ask whether the HAS_INDEX macro is worthwhile, and I tried the same example without it, which pushed the microbenchmark up to 157ms. So it seems it's worth it to avoid the function call to IN() if we know we're dealing with arrays and numbers.

This adds a common perf configuration for JSTests including Classes, Collections, Iterators and Strings. This allows the android test runner to handle subdirectories correctly and to share the base.js resource in the parent directory. The new json config has added resources configs for the Android runner. The perf runner's relative paths on the device are fixed as well. Resources are only pushed on the configuration node where they are specified. They are pushed to a dir on the device that follows the same directory structure as on the host. The binary is executed in the benchmark folder on the device like on the host to allow relative path file loading.
