Currently, these section names have wrong syntax for Mach-O.
Although they were added some time ago; recently added tests are
now emitting them leading to new fails on Darwin.
This adds a Mach-O variant for each.

The following makes reduction epilogue code generation handle missing
LC PHIs for the reductions, in particular also avoid replacing results
on one exit with epilogue result from another one (but not avoiding
generation of dead epilogues yet). The proper fix should be eventually

Oh! I thought this went in as part of the original cartesian_product

sorry.

PR 108007 is another manifestation where we rely on DCE to clean-up
