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

Constant and global may alias, also one rules table wasn't
ordered correctly.
Pinpointed by Matt.
v2: add a test with swapped parameters

Some buildbot slaves reports compilation errors, but it
compiled fine on my side, sorry for the breakage.

Note: This is a candidate for LLVM 6.0, because it was planned to be
in that release but was delayed due to a long review period.
Merge conflict in release_60 - resolution:
Add "-p6:32:32" into the second (non-amdgiz) string.
Only scalar loads support 32-bit pointers. An address in a VGPR will
fail to compile. That's OK because the results of loads will only be used
in places where VGPRs are forbidden.
Updated AMDGPUAliasAnalysis and used SReg_64_XEXEC.
The tests cover all uses cases we need for Mesa.

Summary:
This commit adds comments on how the AMDPAL OS type overloads the
existing AMDGPU_ calling conventions used by Mesa, and adds a couple of
new ones.

I did this a long time ago with a janky python script, but now
clang-format has built-in support for this. I fed clang-format every
line with a #include and let it re-sort things according to the precise
LLVM rules for include ordering baked into clang-format these days.
I've reverted a number of files where the results of sorting includes
isn't healthy. Either places where we have legacy code relying on
particular include ordering (where possible, I'll fix these separately)
or where we have particular formatting around #include lines that
I didn't want to disturb in this patch.
This patch is *entirely* mechanical. If you get merge conflicts or
anything, just ignore the changes in this patch and run clang-format
over your #include lines in the files.
Sorry for any noise here, but it is important to keep these things
stable. I was seeing an increasing number of patches with irrelevant
re-ordering of #include lines because clang-format was used. This patch
at least isolates that churn, makes it easy to skip when resolving
conflicts, and gets us to a clean baseline (again).

Add hasParamAttribute() and use it instead of hasAttribute(ArgNo+1,
Kind) everywhere.
The fact that the AttributeList index for an argument is ArgNo+1 should
be a hidden implementation detail.

Our final address space mapping is to let constant address space to be 4 to match nvptx.
However for now we will make it 2 to avoid unnecessary work in FE/BE/devlib
about intrinsics returning constant pointers.

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.
