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.

This is based off of the GitHub repository

The only remaining difference currently is block-scoping, which is still
implied by --harmony, to avoid regressing on a long-available feature.

Also removes the special-casing of --harmony-proxies.

90a7f07489 Implement loop variable assignment analysis. 
This analysis computes the set of variables that are assigned in each loop. This is useful to avoid creating redundant loop phis when building an SSA graph, which just waste memory and require analysis to get rid of.

This CL implements an AST walk for the analysis and plugs the result into the TurboFan graph builder. I left this analysis under a flag for A/B testing and until sufficient unit tests can be developed.

Currently, the behaviour is essentially the same as ES262's version, however this changes when internal structures
such as Promise make use of symbolToStringTag (as they are supposed to, see v8:3241), and changes further once
Symbol.toStringTag is exposed publicly.

Causes a flaky failure on buildbots. Here is the (deterministic) repro step (thanks to Michael Stanton):

first go to flag-definitions.h and set this to false.

DEFINE_BOOL(enable_sse4_1, false,
            "enable use of SSE4.1 instructions if available")

Run the following and it should fail:

Reland fixes:
 - size_t conversion for 64bit arches
 - Don't call front() on empty vector
   (triggers assertion on windows)
 - turbo_inlining now implies turbo_types, as
   it requires simplified lowering.

1b5848c210 Some fixes to avoid breakages when enabling out-of-line constant pools. 
Three fixes which are required to pass all the tests when  out-of-line constant
pools are enabled for Arm:

 - Invalidate embedded objects in optimized code when it is deoptimized such
   that the weak pointers in the constant pool array are cleared.  This prevents
   a CHECK(heap_->mark_compact_collector()->IsMarked(object)) error when a
   verifying weak pointers in a deoptimized code object's constant pool.
 - Modify LargeObjectSpace::Verify to allow constant pool arrays in the
   large object space.
 - Increase the 32bit stack size limit, since the constant pool pointer
   is now on every stack frame, causing the size of each stack frame to
   increase by one word, and causing deep-recursion-test to fail.

70da8959bc 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.

a0f6878a06 Add mips64 port. 
Summary:

- Changes in common code are mainly boilerplate changes,
gyp and test status files updates.

- On mips64 simulator all tests pass from all test units.

- Current issues: mjsunit JS debugger tests fail randomly on HW in release mode.
Corresponding tests are skipped on HW.

- Skipped tests on mips64: test-heap/ReleaseOverReservedPages, mjsunit/debug-*

7367720daa 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 ParseFunctionLiteral(),
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 ParseExpression() expects parenthesized expressions
to not be empty, so checking for a closing parenthesis is added in
handling the empty parameter list "()" will accept a right-paren and
return an empty expression, which means that the parameter list is
empty.

Additionally, this adds the following machinery:

 - A runtime flag "harmony_arrow_functions" (disabled by default).
   Enabling "harmony" will enable it as well.
 - An IsArrow bit in SharedFunctionInfo, and accessors for it.
 - An IsArrow bit in FunctionLiteral, accessorts for it, and
   a constructor parameter to set its value.
 - In ParserBase: allow_arrow_functions() and set_allow_arrow_functions()
 - A V8 native %FunctionIsArrow(), which is used to skip adding the
   "function " prefix when getting the source code for an arrow
   function.
