a09832ab76 Optimize loads from variables that might be shadowed by variables 
introduced by eval.

In the cases where calls to eval have not introduced any variables, we
do not need to perform a runtime call.  Instead, we verify that the
context extension objects have not been created and perform a direct
load.

Not implemented for ARM yet and the scope resolution code could use
some better abstractions.  I'd like to do that in a separate
changelist.

a23fd3284a Added the simplest call stack sampling and call profile in tick processor output. 
Currently only two stack frames are sampled (current function and its caller).

Output of tick processor looks like this:

 [Call profile]:
   total  call path
   15.2%  LazyCompile: am3 crypto.js:108  <-  LazyCompile: montReduce crypto.js:583
    6.5%  LazyCompile: am3 crypto.js:108  <-  LazyCompile: bnpSquareTo crypto.js:431
    2.9%  Builtin: KeyedStoreIC_Generic  <-  LazyCompile: montReduce crypto.js:583
    2.3%  LazyCompile: am3 crypto.js:108  <-  LazyCompile: bnpMultiplyTo crypto.js:415

Tested under Windows, Linux and OS X.

577741308b First step in refactoring the logging system to allow the logging messages to have other destinations than an open file. 
This change introduces a log message builder which builds the log message in a static string buffer instead of formatting the log message through fprintf. Currently this message can only be written to a file afterwards.

Changed the code related events to use the log message builder.

85584333f9 Support for building V8 with MinGW 
V8 can now be build with MinGW. It still fails the following four tests in debug mode:

  mjsunit/parse-int-float
  mjsunit/mirror-array.js
  mjsunit/integer-to-string.js
  mjsunit/regress/regress-114.js

Building with MinGW has been tested with version 5.1.4 using GCC 3.4.5.

In addition to supporting MinGW this change also makes it more explicit which targets needs to link with which libraries.

Choice nodes may know that they are never not at the start of input.
This can remove start_of_input assertions in cases where they are statically known to fail.
The initial loop is unrolled once if the regexp might check for the start of input. Only the first iteration may be at the start, the following loop knows that it isn't.

3835e915c4 Adding src_file_name:line_number into perf log entries for compiled JS functions. 
Thus, instead of the following profiler records:
   1.5%    1.5%   LazyCompile: <anonymous>
we'll now have these:
   1.5%    1.5%   LazyCompile: <anonymous> richards.js:309

Basically, I translated two functions from messages.js into C++.
In the next CL I will update messages.js to use added native functions.
