For substrings of non-flat cons strings, we bail out to runtime. For single character substrings, we forget to flatten it. This causes successive bailouts.

This way we get all the Crankshaft goodness and avoid always going through the runtime: Less code + even some small speedup in Kraken.

It now closely resembles the js2c target, so that we only have one platform to run it on (either 'host' or 'target'). This way we do not run into warnings when compiling for e.g. ARM.

Port r18046 (99c7352) Original commit message: A performance regression in array literal creation was caused by refactoring that eliminated a special fast case for shallow arrays. At the same time the general case got a bit slower. This CL restores most of the performance without coding the special fast case. The virtual dispatching is unnecessary because we know what we want to do at compile time. A flag was added to Runtime::CreateArrayLiteral. The flags delivers information about shallowness but also whether or not allocation mementos should be created. This is useful for crankshafted code.

Transformed variant flags into named variants. Now, all combinations of variants can be specified on the command line. The old command-line flags are kept for backwards compatibility on the bots. Added two new test groups: slow and pass|fail. Both are implemented similar to the flaky test feature and allow to either skip or run tests marked as slow or as pass|fail.

In this change, the support comes in two flavours: --perf_jit_prof - outputs the files in a new perf format that only works with a patched perf tool (patch obtained from Stephane Eranian). Both 'perf report' and 'perf annotate' are supported (the file format also contains the machine code). --perf_basic_prof - outputs the files in a format that the existing perf tool can consume. Only 'perf report' is supported. In both cases, we have to disable code compaction because the perf tool does not understand code relocation. (We are told that code relocation should be supported soon.) Usage: perf record -g d8 --perf_jit_prof --no_compact_code_space my.js perf report The change itself is straightforward - we simply listen to code events and write an entry to a log file for every new piece of code. I am not yet sure whether we should keep both versions or just one (and which one). My hope is the reviewers can help here.

This commit fixes a lot of test failures that we saw earlier in the buildbots (http://build.chromium.org/p/client.v8/builders/V8%20Linux%20-%20mips%20-%20sim/builds/3034/steps/Check/logs/stdio). In some very rare cases the code age stub address can be 0xXXXX0000 and in this case the li maco instruction emits only 1 instruction (instead of the expected 2). Thus the code age sequence will be 6 instructions long instead of 7, which breaks the code aging feature. This change makes sure that li always emits 2 instructions and it also simplifies the code aging sequence. Also fixes a small mistake in the simulator at the jalr instruction.
