Auto merge of #46457 - m4b:no_mangle_static, r=michaelwoerister
Don't set the linkage_name for static variables
For `no_mangle` statics:
1. Linkage_name no longer set
2. The static variable also no longer has a dwarf namespace scope
This matches C++ output, which does not set the linkage_name and is not scoped:
e.g. c++:
```
0x000000b6: DW_TAG_base_type [8]
DW_AT_name [DW_FORM_strp] ( .debug_str[0x00000077] = "long int")
DW_AT_encoding [DW_FORM_data1] (DW_ATE_signed)
DW_AT_byte_size [DW_FORM_data1] (0x08)
0x000000bd: DW_TAG_variable [9]
DW_AT_name [DW_FORM_strp] ( .debug_str[0x00000053] = "TEST")
DW_AT_type [DW_FORM_ref4] (cu + 0x0048 => {0x00000048})
DW_AT_external [DW_FORM_flag_present] (true)
DW_AT_decl_file [DW_FORM_data1] ("/home/m4b/tmp/bad_debug/test.cpp")
DW_AT_decl_line [DW_FORM_data1] (14)
DW_AT_location [DW_FORM_exprloc] (<0x9> 03 40 10 20 00 00 00 00 00 )
0x000000d2: DW_TAG_namespace [2] *
DW_AT_name [DW_FORM_strp] ( .debug_str[0x0000009d] = "std")
```
and (now) Rust:
```
0x0000002a: DW_TAG_variable [2]
DW_AT_name [DW_FORM_strp] ( .debug_str[0x00000046] = "TEST")
DW_AT_type [DW_FORM_ref4] (cu + 0x0045 => {0x00000045})
DW_AT_external [DW_FORM_flag_present] (true)
DW_AT_decl_file [DW_FORM_data1] ("/tmp/test.rs")
DW_AT_decl_line [DW_FORM_data1] (8)
DW_AT_alignment [DW_FORM_udata] (1)
DW_AT_location [DW_FORM_exprloc] (<0x9> 03 c0 4d 06 00 00 00 00 00 )
0x00000040: DW_TAG_namespace [3] *
DW_AT_name [DW_FORM_strp] ( .debug_str[0x0000004b] = "test")
```
