Currently BOLT finds LSDA secition by it's name .gcc_except_table.main .
But sometimes it might have suffix e.g. .gcc_except_table.main. Find
LSDA section by it's address, rather by it's name.
Fixes#71804
The golang support creates 2 new data segments, one of them contains
relocations in PIC binaries, so the section must have writable rights.
Currently BOLT creates only one new segment that contains new sections
with RX rights, now also create RW segment if there are any new writable
sections were allocated during BOLT binary processing.

I put it into wrong directory. As the result it is failing for aarch64. Moving
the test under X86. Orignial diff D126999.

Address X86 tests failures on AArch64 builder:
https://lab.llvm.org/staging/#/builders/211/builds/82
Inputs fail to cross-compile due to a missing header:
```
/usr/include/stdio.h:27:10: fatal error: 'bits/libc-header-start.h' file not found
#include <bits/libc-header-start.h>
```
As inputs are linked with `-nostdlib` anyway, don't include stdio.h.

The bfd linker adds the symbol versioning string to the symbol name in symtab.
Skip the versioning part in order to find the registered PLT function.

Summary:
This patch adds AArch64 relocations handling in case updating of
debug sections is enabled
Elvina Yakubova,

(cherry picked from FBD33077609)
Summary:
Currently, RuntimeDyld will not allocate a section without relocations
even if such a section is marked allocatable and defines symbols.
When we emit .debug_line for compile units with unchanged code, we
output original (input) data, without relocations. If all units are
emitted in this way, we will have no relocations in the emitted
.debug_line. RuntimeDyld will not allocate the section and as a result
we will write an empty .debug_line section.
To workaround the issue, always emit a relocation of RELOC_NONE type
when emitting raw contents to debug_line.
