Subject: [PATCH] [RuntimeDyld] RuntimeDyldELF: Clear GOTOffsetMap when
resetting GOT section.
When the GOT section ID is reset, the GOTOffsetMap must also be cleared,
otherwise spurious matches can be located when handling GOT relocations
in subsequently-linked objects.
Fixes Issue #61402 - see https://github.com/llvm/llvm-project/issues/61402.
