4f80c064 - [runtimes][NFC] Consistently declare main() functions in tests (#162548)

[runtimes][NFC] Consistently declare main() functions in tests (#162548) In the libc++ test suite, we consistently declare main() functions with full parameters and explicitly return from the function. This helps code that compiles the tests with -ffreestanding, where main() is not a special function (with an implicit return and special mangling). This patch fixes a few stray declarations, including in libunwind and libc++abi.
