THRIFT-2676 Avoid 'i386' name collision in generated Cocoa/objc code
[THRIFT-2676](https://issues.apache.org/jira/browse/THRIFT-2676)
This fixes a bug in the cocoa code generator where the variable
used by a for-loop can conflict with a built-in symbol when the
temporary variable counter is equal to 386. The generated variable
name, 'i386', conflicts with a macro built-in to the compiler.
I can reproduce this bug on Xcode 5 as well as Xcode 6. It appears
to only affect iOS projects, not OS X projects.
My fix simply prefixes the generated variable with 'idx' instead of 'i'.
This test code demonstrates the problem, regardless of Thrift codegen.
```
int i386 = 42;
printf("foobar %d\n", i386);
```
Which results in the following compiler error:
```
/Users/keith/Desktop/ReservedSymbolTest/ReservedSymbolTest/ViewController.m:22:7:
error: expected identifier or '('
int i386 = 42;
^
<built-in>:143:14: note: expanded from here
^
1 error generated.
```
