srdjan@google.com 2c6d0181e1 Fix performance regression introduced by new equality semantic: we do not collect ICData when comparing with NULL. For now recognize left/right inputs as being null constant and convert the equality tests to strict-equality. There is still a problem if one of the equality arguments is always null but not a constant.

fschneider@google.com 253c3f8499 Implement class id checks as a separate instruction and add a local CSE optimization pass.
This CL contains:
A new CheckClassComp instruction. Currently it is used only for instance loads:
(LoadInstanceFieldComp)

A pass LocalCSE that performs block-local common subexpression elimination. To identify
redundant expressions I use a hash map per basic block. Computations that do not have
side effects can participate in CSE. For now, I only enabled it for CheckClass.
Any computation that participates in CSE must implement the AttributesEqual function.


Other smaller fixes:

Places where we can pass the correct initial size for GrowableArrays
that have a known size. We should consider having a FixedLengthArray for this purpose.

Made the accessors ic_data() and set_ic_data() use a const ICData*.

fschneider@google.com df23e58a2f Change indexed load and store IL instructions to fit with SSA backend.
Generic indexed operations are implemented as normal instance calls. Specialized
operations are inserted by the flow-graph optimizer. This also avoid a lot of duplicated code
in the code generator.

fschneider@google.com 94fa6055ab Optimize expressions of the form (expr === true) when expr has boolean type.
This allows us to generate better code for many short-circuit
expressions like a || b, a && b if we can statically determine the type
of the subexpressions.

Also: Avoid disassembling optimized functions twice with --disassemble --disassemble-optimized.
