Jordan Rose 011bda8031 Revert "intmax_t is long long on Darwin, not long." 
'long' and 'long long' are different for the purposes of mangling.
This caused <rdar://problem/13254874>.

This reverts commit c2f994d31ec85e9af811af38eb1b28709aef0b2c.

Jordan Rose aa7a3b3e75 Format strings: correct signedness if already correcting width (%d,%u). 
It is valid to do this:
  printf("%u", (int)x);

But if we see this:
  printf("%lu", (int)x);

...our fixit should suggest %d, not %u.

Jordan Rose ea0fdfe146 Format strings: add more expression types that don't need parens to cast. 
No functionality change (the test change is a comment only, and the new
functionality can't be tested using the current test).

Jordan Rose 4c266aa371 Format strings: offer a fixit for Darwin's %D/%U/%O to ISO %d/%u/%o.

Jordan Rose 510260c2bf Format strings: %D, %U, and %O are valid on Darwin (same as %d, %u, %o). 
These will warn under -Wformat-non-iso, and will still be rejected
outright on other platforms.

Jordan Rose aee3438195 Format strings: suggest casts for NS(U)Integer and [SU]Int32 on Darwin. 
These types are defined differently on 32-bit and 64-bit platforms, and
trying to offer a fixit for one platform would only mess up the format
string for the other. The Apple-recommended solution is to cast to a type
that is known to be large enough and always use that to print the value.

This should only have an impact on compile time if the format string is
incorrect; in cases where the format string matches the definition on the
current platform, no warning will be emitted.
