Matt Arsenault 779cba79ec AMDGPU: Remove mayLoad/mayStore from some side effecting intrinsics
These don't really modify any memory, and should not expect memory
operands.

Francis Visoiu Mistrih 25528d6de7 [CodeGen] Unify MBB reference format in both MIR and debug output
As part of the unification of the debug format and the MIR format, print
MBB references as '%bb.5'.

The MIR printer prints the IR name of a MBB only for block definitions.

Matt Arsenault 3dbeefa978 AMDGPU: Mark all unspecified CC functions in tests as amdgpu_kernel
Currently the default C calling convention functions are treated
the same as compute kernels. Make this explicit so the default
calling convention can be changed to a non-kernel.

Converted with perl -pi -e 's/define void/define amdgpu_kernel void/'
on the relevant test directories (and undoing in one place that actually
wanted a non-kernel).

Jan Vesely e8cc395e4f AMDGPU/GCN: Exit early in hazard recognizer if there is no vreg argument

Matt Arsenault d6adfb401c AMDGPU: Add cache invalidation instructions.
These are necessary for implementing mem_fence for
OpenCL 2.0.

The VI assembler tests are disabled since it seems to be
using the wrong encoding or opcode.
