verifier when -Cpjvmdalvik is used (including debug information). Using
-Cpjvmdalvik changes the semantics at the language-level in one case:
boolean(bytevar) will no longer return a boolean that contains the same
value as bytevar did, but will map the value to 0/1 (that also means that
such expressions cannot be passed to var-parameters in case of
-Cpjvmdalvik). Code compiled with -Cpjvmdalvik will also work fine on
the regular JVM, but it may be somewhat slower (it won't necessarily
be slower on Dalvik, because the .class -> .dex transformation
applies many optimizations itself)
