Leading comma in section name when running tests under MacOS

[volsa]

Describe the bug Currently cargo test will fail with snapshot diffs because a leading comma is appended to the section names. For example the test multiple_files_with_debug_info will fail due to

-define i16 @main() section "fn-main:i16" !dbg !10 {
+define i16 @main() section ",fn-main:i16" !dbg !10 {

-declare !dbg !18 void @mainProg(%mainProg*) section "fn-mainProg:v"
+declare !dbg !18 void @mainProg(%mainProg*) section ",fn-mainProg:v"

-define void @mainProg(%mainProg* %0) section "fn-mainProg:v" !dbg !10 {
+define void @mainProg(%mainProg* %0) section ",fn-mainProg:v" !dbg !10 {

I'm unsure if this is a MacOS thing or ARM in general but I suspect the former.

To Reproduce Under MacOS 14.4.1 switch to the master branch and run cargo t

Expected behavior The snapshots shouldn't change

Hmm, maybe this isn't a bug after all? Inkwell does this intentionally here https://github.com/TheDan64/inkwell/blob/d916c66d2cedb8bc58c187df8403d9fc71eb0ad4/src/values/mod.rs#L219

I tried fixing the snapshot tests under MacOS, removing these leading commas for all tests in the codegen/ folder such that the IR is identical to the master branch. While its working (see https://github.com/PLC-lang/rusty/compare/macos-codegen) the correctness and integration tests fail with a sigbus panic. Not sure why, but the section names seem to cause the panic under MacOS. This needs further investigation...

here is little bit more info for this one when someone needs to look into this.
