LOG: [ORC-RT][LoongArch] Add initial support for loongarch64 in ELFNixPlatform (#123575)
Enable ELFNixPlatform support for loongarch64. These are few simple
changes, but it allows us to use the orc runtime in ELF/LoongArch64
backend.
This change adds test cases targeting the LoongArch64 Linux platform to
the ORC runtime integration test suite. Since jitlink for loongarch64 is
ready for general use, and ELF-based platforms support defining multiple
static initializer table sections with differing priorities, some
relevant test cases in compiler-rt for ELFNixPlatform support can be
enabled.
