2nd attempt after rollback.
Move EnhancedForStatement reconstruction to Rewriter so that it can benefit from additional translation passes.
In particular, this resolves an autoboxing issue.

Allow passing -X* arguments to java via j2objc script. This allows increasing the java heap size and remote debugging, among other things. Makefiles can provide these arguments via the J2OBJC_DEBUGFLAGS variable.

Added -begin-java-args and -end-java-args to j2objc.sh.

The previous attempt to pass arguments to java filtered out arguments beginning with -X. This approach doesn't always work because:
1. there are some java arguments that don't begin with -X
2. there are some j2objc arguments that do begin with -X

Change Java language spec level to support hexadecimal floating point literal
translation. This is necessary because hex FP literals were added to Java 6,
but not spec'd until JLS 3, which confused JDT's AST re-scanner.

Also made @autoreleasepool generation standard, since we now require
a minimum of iOS 5.0.
