Make LeakSanitizer happy, part 2. Fixed register usage on the way.

Note that according to the System V ABI for AMD64, rbx must be
preserved across calls. We actually crash with clang in the x64
assembler tests without that fix, we were lucky with GCC.

[Sheriff] Revert "Check elimination temporarily disabled.", "Fix for buildbot failure after r19102." and "Check elimination improvement: propagation of state through phis is supported, CheckMap narrowing implemented."

This reverts commit r19102, r19105 and r19170 for breaking the
Chrome browser_tests. Will reland once fixed.

Unify PreParser::ParseIdentifierName and Parser::ParseIdentifierName.

No special handling for keywords is needed, since the literal ascii strings for
them work too (see how Parser did it).

Make Function.length and Function.name configurable properties.

ES6 makes the Function object properties "length" and "name"
configurable; switch the implementation over to follow that.

Doing so exposed a problem in the handling of non-writable, but
configurable properties backed by foreign callback accessors
internally. As an optimization, if such an accessor property is
re-defined with a new value, its setter was passed the new value
directly, keeping the property as an accessor property. However, this
is not correct should the property be non-writable, as its setter will
then simply ignore the updated value. Adjust the enabling logic for
this optimization accordingly, along with adding a test.
