Insert representation changes before doing range analysis and fix a bug in Range::Copy.
...
This improves our static type information by calculating the result type
of conversions (HChange) during range analysis. It allows e.g. to eliminate
the write barrier in the following example where it was not possible before:
function f(x) {
var y = x + 1;
if (y > 0 && y < 100) {
a[0] = y;
}
}
* Fix bug in Range::Copy. The minus-zero flags has to be preserved by default.

Improve memory usage of receiver type feedback.
...
Some AST nodes (Property, Call, etc.) store either a list of receiver
types or a monomorphic receiver type. This patch merges the two fields
using a small pointer list. GetMonomorphicReceiverType() is now a
purely convenience function returning the first and only recorded
type.
This saves about 500K (of about 39M) on average when compiling V8
benchmark as measured by a simple patch adding a zone allocation
counter (https://gist.github.com/1149397 ).

Add FIXED_DOUBLE_ARRAY_TYPE to INSTANCE_TYPE_LIST_ALL in objects.h
...
Leaving this out can cause crashes when running with --heap-stats (but this is only used when reporting heap statistics, so this is not a stability issue).

Change AddElementsToFixedArray to work on FixedArrayBase rather than JSObject
...
In the process, make ElementsAccessors work internally more seamlessly with FixedArrayBase.

Simplify handling of exits from with and catch.
...
Remove the try/finally used for with and catch. Instead of using
try/finally to handle break and continue from with or catch,
statically track nesting dept and clean up when compiling break or
continue.
And instead of using try/finally to handle throw to handler in a frame
whose pc is inside a with or catch, store the context that the handler
should run in in the handler itself.

Add roundsd instruction to ia32 and use it in optimized Math.floor.
...
It is available platforms that have SSE 4.1 and allows us to handle
negative numbers without deoptimization. Before we would deoptimize
on negative inputs to Math.floor. x64 already uses this instruction.
* Change Math.floor unit test to make sure every test case gets
optimized by changing the source code for each test case.
* Fix HIR debug printing for some instructions.
