A64: Let the MacroAssembler resolve branches to distant targets.

Code generation would fail when assembling a branch to a label that is bound
outside the immediate range of the instruction. A64 is sensitive to this, as the
various branching instructions have different ranges, going down to +-32KB for
TBZ/TBNZ.  The MacroAssembler is augmented to handle branches to targets that
may exceed the immediate range of instructions.

When branching backward to a label exceeding the instruction range, the
MacroAssembler can simply tweak the generated code to use an unconditional
branch with a longer range. For example instead of
    B(cond, &label);
the MacroAssembler can generate:
    b(InvertCondition(cond), &done);
    b(&label);
    bind(&done);

Since the target is not known when the branch is emitted, forward branches uses
a different mechanism. The MacroAssembler keeps track of forward branches to
unbound labels. When the code generation approaches the end of the range of a
branch, a veneer is generated for the branch.

Fixed and improved code for integral division. Fixed and extended tests.

Arithmetic right shifting is *not* division in two's complement
representation, only in one's complement. So we convert to one's
complement, shift, and go back to two's complement. By permutating the
last steps, one can get efficient branch-free code. This insight comes
from the paleozoic era of computer science, see the paper from 1976:

Guy Lewis Steele Jr.: "Arithmetic Shifting Considered Harmful"
ftp://publications.ai.mit.edu/ai-publications/pdf/AIM-378.pdf

This results in better and more correct code than our previous
"neg/shift/neg" dance.

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.

(Pre)Parser: Move ParsePrimaryExpression to ParserBase.

Notes:
- To be able to move the recursive descent functions to ParserBase one at a
time, we temporarily need routing functions from traits to Parser/PreParser,
since the recursive descent functions form a cyclic structure.
- PreParser used to always allow intrinsic syntax. After this CL, it depends on
allow_natives_syntax() which was already in ParserBase.
- This CL also decouples (Pre)ParserTraits better from (Pre)Parser, passing more
information as parameters, so that the Traits don't need to get it from
(Pre)Parser.

(Pre)Parser: Move FunctionState, BlockState and Scope handling to ParserBase.

Notes:
- This removes Parser::FunctionState and PreParser::FunctionState and adds
ParserBase::FunctionState etc.
- Also the scope stacks and function state stacks are moved to ParserBase.
- PreParser::FunctionState didn't add and subtract
JSFunction::kLiteralsPrefixSize (unlike Parser::FunctionState). Since the
actual value of NextMaterializedLiteralIndex is not used in the Preparser,
this change is valid.
- Traits no longer need functions like is_classic_mode(), since now there is a
unified way of getting the information from the FunctionState / Scope.

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.
