Adding a custom lexer for asm.js parsing.
It takes advantage of a number of asm.js properties to simply things:
* Assumes 'use asm' is the only string.
* Does not handle unicode for now (tools don't emit it).
* Combines global + local string table with lexer.

Collect type information for JavaScript variables and display it
in Chrome DevTools.
Design Doc: https://docs.google.com/a/google.com/document/d/1O1uepXZXBI6IwiawTrYC3ohhiNgzkyTdjn3R8ysbYgk/edit?usp=sharing
When debugging JavaScript, it’s helpful to know the type of
a variable, parameter, and return values. JavaScript is
dynamically typed, and for complex
source code it’s often hard to infer types. With type profiling, we
can provide type information to JavaScript developers.
This CL is a proof of concept. It collects type profile for
assignments and simply prints the types to stdout.
The output looks something like this:
#my_var1
#Object
#number
#string
#number
#undefined
#string
#Object
#Object
We use an extra slot in the feedback vector of assignments to
carry the list of types for that assignment. The extra slot is
only added when the flag --type-profile is given.
Missing work:
* Collect data for parameters and return values (currently only assignments).
* Remove duplicates from the list of collected types and use a common base class.
* Add line numbers or source position instead of the variable name.
For now, has a test that compares the stdout of --type-profile in test/message. We
will remove this test when --type-profile is fully integrated in
the debugger protocol. Adding
the test in test/inspector does not work, because the inspector
test itself consists of JavaScript code that would convolute the
output and be non-deterministic under stress.

Instead, we use the constructor_or_backpointer (or null) field, and
rename it to constructor_or_fti_or_backpointer so nobody is confused.
Note that technically, we still have JSFunctions without contexts, as
they're temporarily created in the deoptimizer.

This changes the IR to no longer require single {IfSuccess} projection
nodes unless there is a corresponding {IfException} node that links the
potentially throwing call to an exception handler. This reduces graph
size as well as compilation time when exception handlers aren't present.
The new invariant for potentially throwing nodes is: Nodes that can
potentially throw either have both IfSuccess/IfException projections as
the only control uses and no direct control uses, or no projections at
all and solely direct control uses.

This extends the existing typer for JS-level comparisons to also be
applied on simplified-level number comparisons. Now that nodes having
such operators are introduced early during graph construction, precise
type information has become more important.

Nodes having the {Throw} operator are just used as terminators for
control-flow leaving the function body with an exception completion,
they turn into basic-block terminators within the schedule. Actually
raising an exception is done solely via runtime calls. Hence {Throw}
nodes no longer need any value input.

Marking it as callable makes typeof return 'function' instead of
'object' when invoked on a remote context or object.

Enable using BaseWithIndexAndDisplacement addressing mode for an address
used by multiple load/stores. It can reduce one instruction to calculate
the address and one register to store the address.

v8 allows the embedder to specify a global template to use when
creating a new context. However, v8 does not use the supplied
template directly when creating the global proxy: it creates a
unique template for each global proxy. However, this is problematic
for remote contexts: functions cannot use strict receiver checks
with the remote context, as the global template will never match
the global proxy.
To fix this, remote contexts now also include a remote global
object in the prototype chain that is instantiated with the global
template. This mirrors the way the global proxy is configured for a
full v8 context, and allows strict receiver checks to work.
