Remove erroneous uses of CXX / CXX_target / CXX_host from gyp.

The current gyp config tries to test whether the compiler is an arm / mips
compiler and whether it supports -m32 / -m64 based on a test within gyp.
Unfortunately CXX / CXX_target / CXX_host are no no longer set early enough
in gyp for this to work, and so all of these tests were actually being done
using "$(which g++)" rather than the appropriate CXX_target / CXX_host compiler.

This change removes these dynamic tests and instead bases the decisions on
knowledge of the host / target / v8_target architecture combination. The
the -m32/-m64 flags are set based on host_cxx_is_biarch / target_cxx_is_biarch,
which are set to reasonable defaults of only ia32/x64 or clang compilers
being build for biarch support. The host_cxx_is_biarch / target_cxx_is_biarch
variables can be overriden if required.

Allow benchmarks to provide the standard deviation.

Some benchmarks include their own runner which provides an
overall average and a standard deviation. This enables
extraction of that value similar to the other measurements.

These benchmarks should only be run once. If a benchmarks
specifies multiple runs and provides a standard deviation,
a warning will be issued that makes the build fail on the
buildbot side.

Add script to bump up version on bleeding edge.

The version.cc file will from now on be controlled on
bleeding edge and on trunk. The next version to use will
always be max(bleeding_edge_version, trunk_version) + 1.

The trunk and bleeding_edge versions are not semantically
tied together. The trunk branch can be used to make
independent point releases of bleeding_edge revisions.

The version on bleeding_edge will be increased if:
- the lkgr version is smaller than the version of the latest
revision,
- the lkgr version is not a version change itself,
- the tree is not closed for maintenance.

This will allow chromium to refer directly to bleeding_edge
revisions of v8. The v8 versions will not be unique, but
they will change as often as possible, dependent on the lkgr
cycle time and the frequency this script is called.

fix the vtune support bug.

During https://code.google.com/p/v8/source/detail?r=19925 checkin context bound scripts (Script)
and context unbound scripts (UnboundScript) are Distinguished.

And then Sven Panne helped to fix the vtune support compilation
error in https://code.google.com/p/v8/source/detail?r=20955.

The problem is that there is runtime error for vtune
support.
In our original implementation, we encapsulated and passed v8::internal::Script
to V8 API. It will leads to type check error for current V8::Script definition.

So I changed the Handle<Script> definition in JitCodeEvent
to Handle<UnboundScript>
and add the corresponding change in log.cc.

If you do NOT prefer to change in include/v8.h. I think I can change the definition of
CodeEventLogger::LogRecordedBuffer(...) so that the we can pass the correct
type (JSFunction) as V8::Script to V8 API.

This CL simplifies var / const by ensuring the behavior is consistent in itself, and with regular JS semantics; between regular var/const and eval-ed var/const.

Legacy const is changed so that a declaration declares a configurable, but non-writable, slot, and the initializer reconfigures it (when possible) to non-configurable non-writable. This avoids the need for "the hole" as marker value in JSContextExtensionObjects and GlobalObjects. Undefined is used instead.

Implement handling of arrow functions in the parser

Arrow functions are parsed from ParseAssignmentExpression(). Handling the
parameter list is done by letting ParseConditionalExpression() parse a comma
separated list of identifiers, and it returns a tree of BinaryOperation nodes
with VariableProxy leaves, or a single VariableProxy if there is only one
parameter. When the arrow token "=>" is found, the VariableProxy nodes are
passed to ParseArrowFunctionLiteral(), which will then skip parsing the
paramaeter list. This avoids having to rewind when the arrow is found and
restart parsing the parameter list.

Note that the empty parameter list "()" is handled directly in
ParsePrimaryExpression(): after is has consumed the opening parenthesis,
if a closing parenthesis follows, then the only valid input is an arrow
function. In this case, ParsePrimaryExpression() directly calls
ParseArrowFunctionLiteral(), to avoid needing to return a sentinel value
to signal the empty parameter list. Because it will consume the body of
the arrow function, ParseAssignmentExpression() will not see the arrow
"=>" token as next, and return the already-parser expression.

The implementation is done in ParserBase, so it was needed to do some
additions to ParserBase, ParserTraits and PreParserTraits. Some of the
glue code can be removed later on when more more functionality is moved
to ParserBase.

Additionally, this adds a runtime flag "harmony_arrow_functions"
(disabled by default); enabling "harmony" will enable it as well.

Implement handling of arrow functions in the parser

Arrow functions are parsed from ParseAssignmentExpression(). Handling the
parameter list is done by letting ParseConditionalExpression() parse a comma
separated list of identifiers, and it returns a tree of BinaryOperation nodes
with VariableProxy leaves, or a single VariableProxy if there is only one
parameter. When the arrow token "=>" is found, the VariableProxy nodes are
passed to ParseArrowFunctionLiteral(), which will then skip parsing the
paramaeter list. This avoids having to rewind when the arrow is found and
restart parsing the parameter list.

Note that the empty parameter list "()" is handled directly in
ParsePrimaryExpression(): after is has consumed the opening parenthesis,
if a closing parenthesis follows, then the only valid input is an arrow
function. In this case, ParsePrimaryExpression() directly calls
ParseArrowFunctionLiteral(), to avoid needing to return a sentinel value
to signal the empty parameter list. Because it will consume the body of
the arrow function, ParseAssignmentExpression() will not see the arrow
"=>" token as next, and return the already-parser expression.

The implementation is done in ParserBase, so it was needed to do some
additions to ParserBase, ParserTraits and PreParserTraits. Some of the
glue code can be removed later on when more more functionality is moved
to ParserBase.

Additionally, this adds a runtime flag "harmony_arrow_functions"
(disabled by default); enabling "harmony" will enable it as well.
