1d1186de - [llvm-exegesis] Add loop-register snippet annotation (#82873)

[llvm-exegesis] Add loop-register snippet annotation (#82873) This patch adds a LLVM-EXEGESIS-LOOP-REGISTER snippet annotation which allows a user to specify the register to use for the loop counter in the loop repetition mode. This allows for executing snippets that don't work with the default value (currently R8 on X86).
