Initial changes made by XCode for my code sign identity and repositories
Remove command line arguments not supported by XCode 5.1
Update Dropbox SDK to version 1.3.10 for 64bit support
Cast pointers to uintptr_t rather than int as they will be longer than an int on 64bit architecture
Add new DESMUME_PLATFORM_STRING for 64bit ARM
Don’t redefine jit_gpr_t and jit_fpr_t to int if running on arm 64
Fix release switches - accidentally removed prefetch-loop-arrays instead of variable-expansion-in-unroller
Use uintptr_t in AllocCacheAlign rather than a u32, as it needs to be a 64bit align mask on 64bit arch.
