[TableGen] Rename ResourceCycles and StartAtCycle to clarify semantics

[michaelmaitland]

Summary

D150312 added a TODO:

TODO: consider renaming the field StartAtCycle and Cycles to
AcquireAtCycle and ReleaseAtCycle respectively, to stress the
fact that resource allocation is now represented as an interval,
relatively to the issue cycle of the instruction.

This patch implements that TODO. This naming clarifies how to use these
fields in the scheduler. In addition it was confusing that StartAtCycle was
singular but Cycles was plural. This renaming fixes this inconsistency.

Thank you for doing this @michaelmaitland.

Patch looks great. Just one minor thing. I believe there is a typo all across the patch: it should be Acquire, not Aquire.

This is very useful, thank you.

File name has typo too.

[michaelmaitland]

It is spelled Acquire, not Aquire... (:embarrased:)

[michaelmaitland]

I am failing build and will look into it. I built all targets locally and had no problem, but perhaps I missed something.

[michaelmaitland]

Rebase.

SystemZ Cycles -> ReleaseAtCycle

Is there any example show how AcquireAtCycles can be used to model scheduling? It's all 0s by default? I don't really understand how it works. :-)

Working on improving the SiFive7 to use it. Will add you as reviewer once posted.

You can watch the talk that describes what StartAtCycle (which became AcquireAtCycle) is for: https://www.youtube.com/watch?v=XWBVLcdzmFg

Oh thanks! That's really helpful! I understand it now, thanks for your admirable works! :-)
