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.

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

also have None as required input representation (e.g. HTest)

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.

Refactor construction of polymorphic loads, stores, and calls.
Rather than passing in a pair of unequal-length lists, pass the default
subgraph separately. Construct the typecase from the top down rather than
the bottom up, so it doesn't need an intermediate zone list.
Also, change a basic block's 'last' instruction field to really be its last
instruction by correctly updating it when inserting and removing
instructions.

Strict mode delete of non-configurable property.
Strict mode flag is passed to runtime DELETE function
and then to JSObject::Delete(Property/Element) as STRICT_DELETION enum.
When deleting non-configurable property/eleemnt, TypeError is thrown.
Adding mozilla test to .gitignore.

Introduce new runtime function to make join with lower memory usage.
Do not use generic StringBuilderConcat which requires array passed
to keep both elements and separator (which roughly double size
of the array). That should be faster as well.
