ea8312ba33 Reapply: Never use classic code generator.
Crankshaft is now the default on all platforms. This is the first
patch on the way to removing the classic code generator from the
system.

This time with no removal of the crankshaft flag. --nocrankshaft is
not at all the same as --always-full-compiler which I had used instead
for testing. That was what caused timeouts on the buildbots because of
repeated attempts to optimize hot functions. It makes sense to keep
the crankshaft flag in case you want to run only with the full
compiler and with no adaptive compilation.

SetElement can cause an exception to be thrown. If its return value

In some cases, it's a matter of returning Exception::Failure() from

to setting directly on a FixedArray and only creating the JSArray
at the end.

b4ff318e4b Support StringCharCodeAt in hydrogen/lithium.
This patch adds H- and L-variants of StringCharCodeAt and StringLength.

StringCharCodeAt is used to inline a constant function call of
String.prototype.charCodeAt and to implement the corresponding inline
runtime function. It does not yet use the recently introduced extra IC
state. (We can specialize on string encoding and avoid deopts because
of out of bounds accesses.)

StringLength needs more work because the stub version of it also
supports strings wrappers and it matters in some cases. (We have to
separate the string only case.)

that goes to runtime as usual but then instead of going megamorphic
generates a monomorphic stub with the updated state.

e21d76a0e3 1. Added support for object printing for release mode using the
objectprint=on (defaults to off) option (which defines OBJECT_PRINT).
2. Added the ability to print objects to a specified file instead of
   just stdout.
3. Added a use_verbose_printer flag (true by default) to allow some
   object printouts to be less verbose when the flag is false.
4. Fixed a bug in VSNPrintF() where it can potentially write into an
   empty char vector.

Patch by Mark Lam from Hewlett-Packard Development Company, LP
