Comment (by jwhowarth):

 FYI, so far the only sensible commit that I've identified in llvm 18.x to
 back port to llvm 17.0.6 is this one.

 Reland "[MC][AsmParser] Diagnose improperly nested .cfi frames"
 This showed up when simplifying some large testcase, where the cfi
 directives
 became out of sync with the proc's they enclose.

 Now restricted to platforms that support .subsections_via_symbols.

 This reverts commit 797b68c.

 Fixes: #72802

 Differential revision: https://reviews.llvm.org/D153167

 Unfortunately, this change alone appears to be insufficient to eliminate
 the build failures on Sequoia.
