We need to refactor code to be explicitely shared by the kernel and at
least the tools/ userspace programs, so, till we do that, copy the bare
minimum bitmap/bitops code needed by tools/perf.

Wrapping the kernel headers is dangerous when it comes to arch
headers. Once we wrap asm/types.h, it will also replace the
glibc asm/types.h, not only the kernel one.
This results in build errors on some machines.
Drop this wrapper and do its work from linux/types.h wrapper,
also the glibc asm/types.h can already handle most of the type
definition it was doing (typedef __u64, __u32, etc...).
Todo: Check the others asm/*.h wrappers to prevent from other
conflicts.

Use the kernel bitmap library for internal perf tools uses.
