[AMDGPU][MC] Added missing isCall/isBranch flags

[dp]

Summary

These flags are required for Comgr to annotate jump targets.
This is a supplement for D99955.

I don't know much about comgr. Is it possible to add some kind of testing for this?

[rampitec]

Can you just copy it from pseudo TSFlags?

[dp]

Looks like it is not possible to query values of these flags in assembler and I'm not aware of any other tools that would allow this.
The flags are utilized by MCInstrAnalysis.

Comgr uses MCInstrAnalysis functionality to identify calls and branches:

const MCInstrAnalysis MIA = ...
if (MIA && MIA->isCall(Inst) ...)

I had to test the patch using Comgr.

Sure. I'll update the patch, hopefully it will be simpler.

Updated to address reviewer's comments.
