When Array(0) or new Array(0) is handled by the generated code it is handled
by the same code as Array() and new Array(). For this to work the stack is
tweaked to remove the argument of value 0. However the argc was still passed
as 1 if a call to the runtime system was made.

When the stack is tweaked argc is also changed to 0.

On 'usual' Linux systems in '/proc/self/maps' we encounter two entries
per library: one has 'rw-p' attrs and the other has 'r-xp'. While on
Android, I see 'rwxp' and 'r-xp' (both entries are marked executable.)
So I've added an explicit check for non-writability to leave only a
single record in the log file.

I noticed a funny thing: in StackTracer::Trace "sample.state" is
checked, but it is only assigned after the check. I've put assignment
before the check.

No need to create sub strings for lazy compiles. The scanner will start from the start position provided.

Moved the creating of character streams into the scanner where possible. This uses a input buffer in the scanner class instead of a stack allocated one.

Added a UTF16 buffer for reading external ascii strings (by templating the external two byte string one) as all the source for the builtins are exposed as external ascii strings.
