Subject: [PATCH 1/2] [LoongArch] Always emit symbol-based relocations
regardless of relaxation
This commit changes all relocations to be relocated with symbols.
Without this commit, errors may occur in some cases, such as when
using `llc`, `lto+relax`, or combining relaxed and norelaxed
object files using `ld -r`.
Some tests updated.
