On Windows, long is always 32 bit, thus one can't use long for casting pointers
to integers, on 64 bit architectures.
Instead use long long, which should be large enough.
This avoids errors like "error: cast from pointer to smaller type 'long' loses
information" in this testcase.
This condition only seems to be an error in mingw mode; in MSVC mode
(clang-cl), this is only a warning.

Subject: [PATCH] [analyzer] Fix a test issue in mingw configurations
On Windows, long is always 32 bit, thus one can't use long for
casting pointers to integers, on 64 bit architectures.
Instead use long long, which should be large enough.
This avoids errors like "error: cast from pointer to smaller type
'long' loses information" in this testcase.
This condition only seems to be an error in mingw mode; in MSVC
mode (clang-cl), this is only a warning.
