This patch only add %pc_hi20/%pc_lo12/%plt relocations in order
to be able to generate gnu ld linkable relocation file for the
`hello world` IR :

  @.str = private unnamed_addr constant [14 x i8] c"Hello world!\0A\00", align 1
  
  define dso_local signext i32 @main() nounwind {
  entry:
    %call = call signext i32 (ptr, ...) @printf(ptr noundef @.str)
    ret i32 0
  }
  
  declare dso_local signext i32 @printf(ptr noundef, ...)

This patch also updated some test cases due to new modifiers.
New test: test/MC/LoongArch/Relocations/relocations.s
