Michael Buch cede236fa5 [llvm][DebugInfo] Drop \01 mangling prefix when inserting linkage name into accelerator table (#138852) ...

On some platforms (particularly macOS), a `\01` prefix gets added to the
name in an `asm` label. This gets stripped when we emit the
[`DW_AT_linkage_name`](2f877c2722/llvm/lib/CodeGen/AsmPrinter/DwarfUnit.cpp (L531)).
But we weren't stripping this prefix when inserting the linkage name
into accelerator tables.

This manifested in an issue where LLDB tried to look up a name in the
index by linkage name, but wasn't able to find it because we indexed it
with the `\01` unstripped.

This patch strips the prefix before indexing.
