Right now if you try to run an x86_64 build of JSC under rosetta it won't have JIT.
This is because Rosetta doesn't play nice with some of the security entitlements we
use. Additionally, for historical perfomance reasons we disabled JIT when in a translated
process. This patch adds a new option to build-jsc (--rosetta). The --rosetta option sets
a flag in `process-entitlements.sh` to stop adding the bad entitlements for `jsc` and
other JSC test binaries. The --rosetta option also sets `HAVE_CPU_TRANSLATION_CAPABILITY=0`
making JSC think it's actually running natively.

Also, pass --makeArgs as `GCC_PREPROCESSOR_ADDITONS` in `build-jsc` when building with xcodebuild.
Lastly, do a little code cleanup in buildUpToProject as well.
