kmillikin@google.com 27af144369 Move code around in preparation for better inlining.
To inlining calls in a test context, the code to plug the inlined
function graph into the caller graph should be dispatched on the type
of the inlining context.

This change moves code around without otherwise changing it.

srdjan@google.com 76dffe600c Removed loop depth info tracking at graph build time.
60% compilation speed improvement on pathological case. Improvements for dart2js

The loop depth signal was made unnecessary by the call frequency signal.

kmillikin@google.com 0f65888e88 Change the inlining context from an enum to a class.
To support inlining in test contexts, the inlining context needs to have its
dispatched behavior and state.  This change introduces a context class
representing calls inlined for their value or solely for their effects.  The
intermediate array of exits is moved from the graph to the inlining context.
The implementation behavior is otherwise the same as before.

These instructions do not have their arguments as input operands anymore since they

vegorov@google.com c9e8d9594e Add support for fixed parameters in the register allocator.
This remove bailout for functions with non-zero number of non-fixed parameters and increases our coverage.

SpillSlot location was renamed into StackSlot location and now allows to address spill slots (positive stack index) and incoming parameters (negative stack index).

Environment was reordered to match order of values on the stack (previously it was inversed).

Correctly reserve spill slots in the prologue of the code. Previously register allocator was allocating spill slots, but generated code did not reserve any space for them on the stack so they might have been overwritten by calls.

Fix off by one in DeoptimizationStub::GenerateCode - we were reserving one slot too many.

Change --optimization-filter flag to use substring search instead of prefix comparison, this is much more useful when VM prefixes function name with a path to the file.

kmillikin@google.com 87d743a3c5 Introduce Goto instructions to the flow graph.
Goto is a control instruction with a single successor.

Before: basic blocks ended with an exit (return, throw, or rethrow), a
branch to a pair of target entries, or else they fell through to the
next block entry.

Now: basic blocks end with an exit, a branch, or an explicit goto to a
join entry.

kmillikin@google.com 595aafa18e Simplify adding of computations to the flow graph.
In preparation for collapsing BindInstr/DoInstr and flattening
Computations into the Instruction hierarchy.

Add a pair of functions EffectGraphVisitor::Bind and
EffectGraphVisitor::Do for adding computations to the flow graph that
have respectively one and zero uses.  This creates a single site where
we construct new BindInstr and a single site where we construct new
DoInstr (also, a single site where we construct new UseVal during flow
graph construction).
