Many websites use simple calls to String.prototype.indexOf with either a
one character ASCII needle or needles bigger than the search string. This
CL adds a TFJ builtin for these simple cases, giving up to factor 5 speedup.

Drive-by-fix: Add default Object type to Arguments.at

TurboFan can create ConsStrings with empty first parts (for history on

These crashes were caused by an invalid pointer stored in a tagged
variable in SubStringStub. This can be reproduced by calling the stub on
an external string and ensuring GC kicks in on the subsequent
allocation.

Only the TurboFan implementation of SubStringStub is affected, the current
PlatformStub implementation handles this case just fine.

The previous JavaScript version created way too many ConsStrings for
longer strings, i.e. when using String.fromCharCode together with
Function.prototype.apply and arrays of char codes.

This version now always allocates sequential strings and therefore uses
way less memory when turning longer character sequences into strings,
and therefore fixes the memory regression on Google Maps.

Revert of [regexp] implement /ui to mirror the implementation for /i. (patchset #2 id:20001 of https://codereview.chromium.org/1641613002/ )

Reason for revert:
This test fails:

assertEquals(["as"], /^a[\u017F]/ui.exec("as"));

The reason is that we end up with a character class that is not stand alone, so we do not perform case folding on it correctly (with unicode flag).

Revisit of https://codereview.chromium.org/910333004.

Use 4MB heap page size over the default of 1MB.

This change provides an improvement of 1.86% on the composite octane
benchmark score on PPC. This is 0.56% more than if --min_semi_space_size=4
was used to specify a 4MB heap page size.

Additionally, two more tests required modification to account for
configurable heap page size.

covers the core changes to the common files.  Subsequent patches will cover
changes to common files to support AIX and to update the ppc directories so
they are current with the changes in the rest of the project.
