Add -repeatCount in superpmi.exe to repeat method compilation
#94503
Conversation
Passing `-repeatCount N` for some integer `N > 0` will compile each function `N` times. This is true for each function in the MCH file, by default, or each one specified by a `-c` argument or .mcl file. This can be used to help investigate the JIT throughput for compilation of a particular function or set of functions. This is based on dotnet#93417.

This is based on the work @kunalspathak investigated in #93417. I submitted it as a separate PR because it ended up so different. The most annoying part here was getting the progress report to make sense for the normal case as well as the Percent complete should actually be a little more accurate for the case of specified indexes without TOC, and TOC without specified indexes. |

Note that most of the changes starting here are because everything in the iter loop was indented 4 spaces.

The progress output was moved to the end of the loop because it made all the progress output scenarios work better.
