Deferred function call validation is required to support out of order
asm.js function declaration. Unfortunately, since we've started interleaving
validation and asm-wasm building, we don't check names are resolved until
the end.
Fortunately, undefined names can be detected from their CallType.
Check this at asm-typer time.

Downside: this adds all kinds of weird includes in the .cc files.

Generalize Messages to include an error level.
Add a parameter to AddMessageHandler to select which error levels to receive, using a mask (default being just errors, i.e. the current behavior).

The asm-wasm-builder started allocating SharedFunctionInfos,
this makes it bad we'd passed Script by pointer (due to ignorance).
Switching to Handle<Script>.

Make the AsmWasmBuilder drive the process of typing and potentially parsing
function bodies. This will allow us to keep only a single asm.js function's
AST in memory as we convert to WebAssembly.
This is needed to keep our memory footprint low.
Add some additional output to a few tests that's helpful to see which stage they fail at.

We recently allowed global constants in asm.js validated code.
When used in a return statement, these need to be of an allowed type.

This reduces per-scope overhead from minimally 6 words to 2 words, with one additional pointer per entry, rather than an average of 2 per entry for larger-than-4 element lists. For temp zone parsed functions it additionally makes the declaration-list actually freeable.
This introduces ThreadedList to implement the details of dealing with such a list.

Allow fround to take values without dots for globals (the spec allows this
subtly).
Drop over-restrictive assert preventing floating point globals from working.

Avoid internalizing on-the-fly now that scope analysis and natives syntax
runtime calls no longer require internalized AST values. This should be
more efficient by avoiding extra branches on every AST value creation.

This makes us able to get rid of dependencies to parser.h from places
which only need the ParseInfo, and also gets rid of the curious Parser
<-> Compiler circular dependency.
Also IWYUd where necessary.

The bug was caused when validating expressions
X >> 0
for indexing into 8-bit heap views. If X was not an intish, the 'normal'
validation path would fail. That, however, left the type of X registered
in the AsmTyper::node_types_ member.
Later, in the 'lenient' code path for 8-bit views, the entire X >> 0
expression would be validated, which would cause X to be validated
again, at which point AsmTyper::SetTypeOf() would DCHECK because the
supplied node already had a type associated with it.
The fix was to simply FAIL() when X is not an intish. This is safe
because if X is not an intish, then
Validate(>>, !intish, FixNum)
will also fail.

1) Validation fails for literal indexes too large for accessing a given
heap type
2) Removes the special handling of FloatishDoubleQ, and FloatQDoubleQ;
the inheritance issue that required this special handling was fixed in
another CL.
3) Fix a macro name (from asm_* to ASM_*)
