Matthias Hausner 3e0d13bc28 Make compile-time errors catchable 
If an error happens during the compilation of a function body, an Error is thrown which can be intercepted, and ensures that finally blocks are executed before the isolate is terminated.

The language spec is vague about compilation errors. A doc describing the intentions behind this CL is at
https://docs.google.com/document/d/1_MWOgwJadLCQSBps0zD6Rj5dG4iP1UBuiDvTMH-WMzI/edit#

Example:
     1	void bad() {
     2	    return 5
     3	}
     4
     5	void main(args) {
     6	    bad();
     7	}

Before this CL:
$ dart ~/tmp/e.dart
'file:///Users/hausner/tmp/e.dart': error: line 2 pos 11: semicolon expected
  return 5
          ^
$

After this change:
$ dart ~/tmp/e.dart
Unhandled exception:
'file:///Users/hausner/tmp/e.dart': error: line 2 pos 11: semicolon expected
  return 5
          ^

#0      main (file:///Users/hausner/tmp/e.dart:6:3)
#1      _startIsolate.<anonymous closure> (dart:isolate-patch/isolate_patch.dart:259)
#2      _RawReceivePortImpl._handleMessage (dart:isolate-patch/isolate_patch.dart:148)
$

Notice that the stack trace points to the call site of bad(), not the text location of the syntax error. That's not a bug. The location of the syntax error is given in the error message.
