AMDGPU: Change how exp is printed
...
This is an improvement over a long list of unreadable numbers.
A follow up patch will try to match how sc formats these.

AMDGPU: Refactor exp instructions
...
Structure the definitions a bit more like the other classes.
The main change here is to split EXP with the done bit set
to a separate opcode, so we can set mayLoad = 1 so that it won't
be reordered before the other exp stores, since this has the special
constraint that if the done bit is set then this should be the last
exp in she shader.
Previously all exp instructions were inferred to have unmodeled
side effects.

AMDGPU/SI: Implement a custom MachineSchedStrategy
...
Summary:
GCNSchedStrategy re-uses most of GenericScheduler, it's just uses
a different method to compute the excess and critical register
pressure limits.
It's not enabled by default, to enable it you need to pass -misched=gcn
to llc.

AMDGPU: Add a shader calling convention

This makes it possible to distinguish between mesa shaders
and other kernels even in the presence of compute shaders.
