Turned off PostLink when -debug is true. Flex Builder by default
compiles a debug SWF and for large applications, the time spent
compiling small localized changes are dominated by PostLink, which
includes combining ABC blocks and running the peephole optimizer.
This makes the SWF smaller and faster, but that's not really important
if you are in the middle of active development and have "Build
Automatically" turned on. As a result, we now skip PostLink when
-debug is true. We don't disable PostLink when -verbose-stacktraces
is true, even though Flex Builder also sets this to true by default,
because it's possible to enable -verbose-stacktraces for a production
For a full compile of FlexStore, this change results in about a 7%
speedup. For an incremental build of Dorado with a small, localized
change to an AS file, this change results in about a 58% speedup. In
general, the larger the application and the less time spent in
CompilerAPI.compile(), the more significant the speedup.
