turnidge@google.com 2803d78dfd Change the zone allocation api.
Instead of passing a size in bytes to the allocation function, we now
have a templatized Alloc function:

  zone->Alloc<Type>(len)

This is better for security, as we can check for integer overflow in
the size computation before performing the allocation.  Before, we
often failed to check this.

hausner@google.com 2db691aa14 Better breakpoint management
If a function is already compiled, make a source breakpoint at
the actual breakpoint line number, which may be different from the
requested line number.

srdjan@google.com f6dfa63c9a Cleaned up usage of Function::code, since it may be misunderstood that it points to the only Code object that belongs to that function. That is not the case, there can be several Code object generated for the same function. "Renamed" "code()" to "CurrentCode()", use unoptimized_code where it is clear that we are using unoptimized code only. If compiled, there is a 1:1 correspondence between function and unoptimized code.

turnidge@google.com 0ddd4c04e9 Dart_PropagateError, take 2.
This change hopefully takes care of the non-mac build issues.  The
checked mode failures are fixed in a separate cl.

turnidge@google.com ae88492093 Revert Dart_PropagateError until I can track down the problems in
checked mode tests.

Sorry for the hubbub.

turnidge@google.com 9da62c5fea Add Dart_PropagateError.
This function can be used in native functions to properly pass all
errors up the stack.

Set the long jump base in the Compiler instead of outside of the
compiler.  A bunch of errors that used to be propagated through the
sticky_error are now propagated through return values.  This includes
all of the DartEntry and DartLibraryCall functions.

In particular, we no longer use the long jump to cross dart frames.
Instead errors are propagated across dart frames using the same
mechanism that we use for unhandled exceptions.  I've added assertions
to make sure that we only use the long jump when it is "safe".
