791c9e2c21 Remove most uses of HSubgraph as an argument. 
In a lot of cases where we were passing a subgraph (a pair of basic blocks),
we actually only needed a basic block.

ae328e61b0 Properly reset external catcher if exception couldn't be externally caught. 
We can wrongly assume that exception which is not intended to be caught
by external try/catch should be caught if this exception inherits
external catcher from some previous exception.  To prevent that,
clear external catcher when processing exceptions which cannot be
externally caught.

3af35dc96f Optimize functions needing a local context. 
Allocate the context in the prologue. Two issues had to be solved:
(1) deoptimization needs to handle functions with a local context,
(2) we need a safepoint in the prologue.

56788625b6 Fix CPU profiling for Crankshaft. 
The main issue was due to multiple recompilations of functions.  Now
code objects are grouped by function using SFI object address.
JSFunction objects are no longer tracked, instead we track SFI object
moves. To pick a correct code version, we now sample return addresses
instead of JSFunction addresses.

tools/{linux|mac|windows}-tickprocessor scripts differentiate
between code optimization states for the same function
(using * and ~ prefixes introduced earlier).

DevTools CPU profiler treats all variants of function code as
a single function.

ll_prof treats each optimized variant as a separate entry, because
it can disassemble each one of them.

tickprocessor.py not updated -- it is deprecated and will be removed.

45c63ffa6a Add more generic version of reloc info padding to ensure enough space for reloc patching during deoptimization (fixes issue 1174). 
The old version only added extra space when we did indirect calls, but
the problem remains the same with normal calls that can be represented
as a single byte. When doing patching each call will always be at
least 2 bytes long because we use RUNTIME_ENTY as the reloc mode.

031062d246 Fix bug with input representation of HValueOf. 
The class did not correctly implement the RequiredInputRepresentation.
I changed this functions to be abstract so that all hydrogen classes
must implement it.

As a convention instructions with zero input operands return None as input
representation.

Instructions that can handle all input representations without converting before
also have None as required input representation (e.g. HTest)

All other instructions need a proper required input representation.

2ab5691ac1 ARM: Add support for just one string argument in the string add stub 
Having a string add stub which can handle a string in just one of the arguments is essencial for the type recording binary operation stub when expecting strings. Otherwise string added with e.g. smi will always call the runtime for a type transition which will be back to the same types as the transition code keeps it in string arguments when one argument is a string.

This fixes the regression (especially Delta Blue) caused by replacing the generic binary operation stub with the type recording binary operation stub in the ARM lithium code generator.

c1386c3381 Shorten live ranges for arguments to runtime calls. 
Before, the live ranges of the arguments extended to the call itself, and
they were pushed immediately before the call.  Now, they are spilled eagerly
as soon as their value is available and they are spilled to the right place.

The inlined runtime calls in the optimized backend are changed to work as in
all the other backends: they get their arguments untranslated and can choose
their own custom evaluation order.
