AMDGPU: bump AS.MAX_COMMON_ADDRESS to 6 since 32-bit addr space
32-bit constant address space is declared as 6, so the
maximum number of address spaces is 6, not 5.
Fixes "LLVM ERROR: Pointer address space out of range".
v5: rename MAX_COMMON_ADDRESS to MAX_AMDGPU_ADDRESS
v4: - fix compilation issues
- fix out of bounds access
v3: use static_assert()
v2: add a very simple test for 32-bit addr space

As we introduced target triple environment amdgiz and amdgizcl, the address
space values are no longer enums. We have to decide the value by target triple.
The basic idea is to use struct AMDGPUAS to represent address space values.
For address space values which are not depend on target triple, use static
const members, so that they don't occupy extra memory space and is equivalent
to a compile time constant.
Since the struct is lightweight and cheap, it can be created on the fly at
the point of usage. Or it can be added as member to a pass and created at
the beginning of the run* function.

This is direct port of HSAILAliasAnalysis pass, just cleaned for
style and renamed.
