[REQUEST] Support Intel assembly syntax about osaca HOT 2 OPEN

Hi @pleroy ,
I don't have any experience with the MSVC compiler, I would assume there should be a compiler flag to produce AT&T syntax out of the box, like the -masm=dialect flag for GCC?

Adding Intel syntax support to our parser is on our list of TODOs for a long time, however, we haven't prioritized it so far due to limited resources. If you want to contribute, we would be more than happy about a PR (even just an initial approach we can build on and discuss about together afterwards)!

Hi @JanLJL -- Thanks for your quick reply.

I don't think that there is a flag to ask the MSVC compiler to produce the AT&T syntax (or if there is, it is well hidden). The relevant documentation is here and it doesn't even mention the syntax that it produces. Note incidentally that godbolt displays the Intel syntax, which is not a proof of anything, but a hint that maybe that's the only thing there is for MSVC.

I don't want to put the Intel parser on the critical path of some performance-sensitive code that I am writing, but the time will come when I will really want to do precise latency/throughput analysis. I'll try to split the work in relatively small chunks for ease of review.
