Rollup merge of #53290 - whitequark:fix-35741, r=nagisa
Make LLVM emit assembly comments with -Z asm-comments
Fixes #35741, and makes `-Z asm-comments` actually do something useful.
Before:
```
.section .text.main,"ax",@progbits
.globl main
.p2align 4, 0x90
.type main,@function
main:
.cfi_startproc
pushq %rax
.cfi_def_cfa_offset 16
movslq %edi, %rax
leaq _ZN1t4main17he95a7d4f1843730eE(%rip), %rdi
movq %rsi, (%rsp)
movq %rax, %rsi
movq (%rsp), %rdx
callq _ZN3std2rt10lang_start17h3121da83b2bc3697E
movl %eax, %ecx
movl %ecx, %eax
popq %rcx
.cfi_def_cfa_offset 8
retq
.Lfunc_end8:
.size main, .Lfunc_end8-main
.cfi_endproc
```
After:
```
.section .text.main,"ax",@progbits
.globl main # -- Begin function main
.p2align 4, 0x90
.type main,@function
main: # @main
.cfi_startproc
# %bb.0:
pushq %rax
.cfi_def_cfa_offset 16
movslq %edi, %rax
leaq _ZN1t4main17he95a7d4f1843730eE(%rip), %rdi
movq %rsi, (%rsp) # 8-byte Spill
movq %rax, %rsi
movq (%rsp), %rdx # 8-byte Reload
callq _ZN3std2rt10lang_start17h3121da83b2bc3697E
movl %eax, %ecx
movl %ecx, %eax
popq %rcx
.cfi_def_cfa_offset 8
retq
.Lfunc_end8:
.size main, .Lfunc_end8-main
.cfi_endproc
# -- End function
```
