eaab533fd8 Cleanup the double field tracking in Hydrogen. 
Use a dedicated BuildLoadNamedField() with PropertyAccessInfo,
similar to BuildStoreNamedField() for optimized graph building,
and a dedicated BuildLoadNamedField() for the code stubs, and
don't depend on FLAG_track_double_fields during code generation.

6744ff61ae Fix dictionary element load to pass correct elements kind. 
Using FAST_SMI_ELEMENTS triggers optimization on 64-bit architectures that load
only the higher 32 bits of the element. If the element is a pointer to undefined
that has 0 in the higher half than it is erroneously treated as SMI 0.

8acefb33fe Test and fix for polymorphic named call deoptimization. 
The fix removes wrong simulates from the number branch of polymorphic
call/field access handling.

The change also fixes the same thing for polymorphic named field
access even thourgh the field access is probably safe in practice
(because it cannot deoptimize). It is better to keep all our simulates
in sync with full codegen.

8f170a66e7 Improve positions tracking inside the HGraphBuilder. 
Instead of tracking simple absolute offset from the start of the script like other places do, track a pair of (inlining id, offset from the start of inlined function).

This enables us to pinpoint with inlining path an instruction came from. Previously in multi-script environments we emitted positions that made very little sense because inside a single optimized function they would point to different scripts without a way to distinguish them.

Start dumping the source of every inlined function to make possible IR viewing tools with integrated source views as there was previously no way to acquire this information from IR dumps. We also dump source position at which each inlining occured.

Tracked positions are written into hydrogen.cfg as pos:<inlining-id>_<offset>.

Flag --emit-opt-code-positions is renamed by this change into --hydrogen-track-positions to better convey it's meaning.

In addition this change assigned global unique identifier to each optimization performed inside isolate. This allows to precisely match compilation artifacts (e.g. IR and disassembly) and deoptimizations.

9a0a86fd4c Get rid of the function sorting in for polymorphic calls. 
The idea of this code was to sort functions according to
ticks spend executing them, but now these ticks are always
zero and therefore we fall back to sorting by AST length (or
even worse by source length) all the time, which is a bad,
arbitrary measure.
