[arm64] Optimize fcmp when lhs operand is #0.0
This patch checks the type of the lhs operand of a floating point
comparison, and commutes the operands if it is #0.0. It allows us to
optimize a comparison with zero, as the fcmp instruction accepts #0.0 as
rhs operand.
Code before for "0.0 < 0.123":
------------------------------
fmov d1, xzr
ldr d0, pc+96
fcmp d1, d0
b.lo #+0xc
Code after:
-----------
ldr d0, pc+92
fcmp d0, #0.0
b.gt #+0xc
Before this patch, we used unsigned condition codes for floating point
comparisons, but the unordered case was not correctly commuted.

Don't crash when preparsing destructured arguments
This adds the materialized literal count accumulated while parsing the
parameters (in the parser proper) to that accumulated by the preparser.
This should have been caught in cctest/test-parsing, but it's not covered
because the parsing tests call directly into the preparser rather than
using Parser::ParseFunctionLiteral (which fully-parses the parameters
and then calls into the preparser to skip over the function body).
Note that this further-inflates the materialized literal count for
functions with destructured arguments, since some of the counted
literals are actually binding patterns. But that's not specific to
binding patterns in formal parameters: it happens in function bodies, too.

Implement sloppy-mode block-defined functions (Annex B 3.3)
ES2015 specifies very particular semantics for functions defined in blocks.
In strict mode, it is simply a lexical binding scoped to that block. In sloppy
mode, in addition to that lexical binding, there is a var-style binding in
the outer scope, which is overwritten with the local binding when the function
declaration is evaluated, *as long as* introducing ths var binding would not
create a var/let conflict in the outer scope.
This patch implements the semantics by introducing a DelegateStatement, which
is initially filled in with the EmptyStatement and overwritten with the
assignment when the scope is closed out and it can be checked that there is
no conflict.
This patch is tested with a new mjsunit test, and I tried staging it and running
test262, finding that the tests that we have disabled due to lack of Annex B
support now pass.

Reland of Make profiler no frame region detection code more robust [ia86/x64]
Upon collection of the stack trace if the current PC falls into
the frame building code, the top frame might be in a non-consistent
state. That leads to some of the frames could be missing from the
stack trace.
The patch makes it check instructions under current PC and if they
look like the frame setup/destroy code, it skips the entire sample.

Reland "[test] Fix cctest path separators on Windows"
Now run-tests.py understands "suite/foo/bar" with forward slashes for
command-line test selection on all test suites on all platforms.
Previously, file-based suites like mjsunit also accepted "mjsunit/foo\bar";
that behavior is sacrificed here in favor of unification. For the cctest
suite, OTOH, it wasn't possible on Windows to select specific tests at all.

thread.
- Remove emergency memory (PagedSpace, and CodeRange)
- Introduce partial compaction of pages.
