The SwiftStdint.h header is used in the compiler as well. The compiler may be
built with cl (Visual Studio) on Windows, which does not define
`__INTPTR_TYPE__` nor does it define `__INTPTR_WIDTH__`. Simply define the
`__swift_{,u}intptr_t` typedefs as Microsoft does on that platform when building
with Visual Studio.

// stdint.h is provided by Clang, but it dispatches to libc's stdint.h. As a
|
|
// result, using stdint.h here would pull in Darwin module (which includes
|
|
// libc). This creates a dependency cycle, so we can't use stdint.h in
|
|
// SwiftShims.
|
|
// On Linux, the story is different. We get the error message
|
|
// "/usr/include/x86_64-linux-gnu/sys/types.h:146:10: error: 'stddef.h' file not
|
|
// found"
|
|
// This is a known Clang/Ubuntu bug.
|
|
|
|
// Clang has been defining __INTxx_TYPE__ macros for a long time.
|
|
// __UINTxx_TYPE__ are defined only since Clang 3.5.
