[lld] Add module name to LTO inline asm diagnostic
Close #52781: for LTO, the inline asm diagnostic uses `<inline asm>` as the file
name (lib/CodeGen/AsmPrinter/AsmPrinterInlineAsm.cpp) and it is unclear which
module has the issue.
With this patch, we will see the module name (say `asm.o`) before `<inline asm>` with ThinLTO.
```
% clang -flto=thin -c asm.c && myld.lld asm.o -e f
ld.lld: error: asm.o <inline asm>:1:2: invalid instruction mnemonic 'invalid'
invalid
^~~~~~~
```
For regular LTO, unfortunately the original module name is lost and we only get
ld-temp.o.
