[LoongArch] Emit R_LARCH_RELAX when expanding some macros (#120067)
Emit `R_LARCH_RELAX` relocations when expanding some macros, including:
- `la.tls.ie`, `la.tls.ld`, `la.tls.gd`, `la.tls.desc`,
- `call36`, `tail36`.
Other macros that need to emit `R_LARCH_RELAX` relocations was
implemented in https://github.com/llvm/llvm-project/pull/72961, including:
- `la.local`, `la.pcrel`, `la.pcrel` expanded as `la.abs`, `la`,
`la.global`, `la/la.global` expanded as `la.pcrel`, `la.got`.
Note: `la.tls.le` macro can be relaxed when expanded with
`R_LARCH_TLS_LE_{HI20/ADD/LO12}_R` relocations. But if we do so,
previously handwritten assembly code will occur error due to the
redundant `add.{w/d}` followed by `la.tls.le`. So `la.tls.le` keeps to
expands with `R_LARCH_TLS_LE_{HI20/LO12}`.
