27eb59ae33 MIPS: A performance regression in array literal creation was caused by refactoring. 
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.

4e439deb0b Support for the Linux 'perf report' and 'perf annotate' tools. 
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.

a6be7b0f1a MIPS: Fix and simplify code aging. 
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.

7158b51125 Fix combined string length computation. 
For 31-bit smis, we don't need to explicitly check whether the
combined string length exceeds the max supported string length,
since the value must be converted to a smi at some point (i.e.
when it is stored into the string length field of the resulting
string), which will emit an overflow check.

For 32-bit smis, we insert an explicit check that the combined
string length does not exceed String::kMaxLength.

This also enables to get rid of the JoinContinuation() usage in
BuildUncheckedStringAdd().
