Use a subtarget feature instead of a command line argument to reduce

We want to enable flat scratch for graphics in some cases and this

This reverts commit 640beb38e7710b939b3cfb3f4c54accc694b1d30.
That commit caused performance degradtion in Quicksilver test QS:sGPU and a functional test failure in (rocPRIM rocprim.device_segmented_radix_sort).
Reverting until we have a better solution to s_cselect_b64 codegen cleanup

AMDGPU: Enable fixed function ABI by default
Code using indirect calls is broken without this, and there isn't
really much value in supporting the old attempt to vary the argument
placement based on uses. This resulted in more argument shuffling code
anyway.
Also have the option stop implying all inputs need to be passed. This
will no rely on the amdgpu-no-* attributes to avoid passing
unnecessary values.

AMDGPU: Assume all amdhsa kernarg passed implicit arguments by default
Previously we would require adding an attribute to kernels to enable
the inputs passed in the kernarg segment, accessed by
llvm.amdgcn.implicitarg.ptr. This violates the principle of being
correct by default. Some OpenMP testcases were broken recently since
it wasn't correctly setting this attribute, and no known frontends are
setting this to anything other than the maximum.
Most of the test changes are from load widening of argument loads
since there now more implied dereferenceable bytes.

AMDGPU: Invert ABI attribute handling

indicate when they were necessary.
AMDGPU: Invert ABI attribute handling
Previously we assumed all callable functions did not need any
implicitly passed inputs, and added attributes to functions to
indicate when they were necessary. Requiring attributes for
correctness is pretty ugly, and it makes supporting indirect and
external calls more complicated.
This inverts the direction of the attributes, so an undecorated
function is assumed to need all implicit imputs. This enables
AMDGPUAttributor by default to mark when functions are proven to not
need a given input. This strips the equivalent functionality from the
legacy AMDGPUAnnotateKernelFeatures pass.
However, AMDGPUAnnotateKernelFeatures is not fully removed at this
point although it should be in the future. It is still necessary for
the two hacky amdgpu-calls and amdgpu-stack-objects attributes, which
would be better served by a trivial analysis on the IR during
selection. Additionally, AMDGPUAnnotateKernelFeatures still
redundantly handles the uniform-work-group-size attribute to be
removed in a future commit.
At this point when not using -amdgpu-fixed-function-abi, we are still
modifying the ABI based on these newly negated attributes. In the
future, this option will be removed and the locations for implicit
inputs will always be fixed. We will then use the new attributes to
avoid passing the values when unnecessary.
