fschneider@google.com 71767f5218 Add code for CPU feature detection and use it to detect SSE3 and SSE 4.1. 
The Dart VM now requires at least SSE3 to build and run.

There is a new flag --use-sse41 (default:true) to disable the use of 
SSE 4.1 features manually.

Split it into three phases: initialization, widening and narrowing.

During widening and narrowing phi-ranges change according to classical widening and narrowing operators defined as:

Widening:
  [_|_, _|_] v [a, b] = [a, b]
  [a, b] v [c, d] = [c < a ? -inf : a, d > b ? +inf : b]

Narrowing:
  [a, b] ^ [c, d] = [(a == -inf) ? c : min(a, c), (b == +inf) ? d : max(b, d)]

ager@google.com b065e9cb29 Fix implicit super constructor calls for sub-classes of native field wrappers. 
The current code does not add implicit super calls for any sub-classes
of native field wrappers. It should only omit them from the actual
native field wrappers.

I encountered this issue when looking into dartbug.com/5301.

The test in the parser is not pretty. However, since the native field
wrappers can be generated through the API a better solution was not
immediate. I wanted to check if the class was from the
dart:nativewrappers library, but through the API you can create
native wrappers in any other library as well.
