LoongArch: BPF: Adjust the parameter of emit_jirl()
[ Upstream commit c1474bb0b7cff4e8481095bd0618b8f6c2f0aeb4 ]
The branch instructions beq, bne, blt, bge, bltu, bgeu and jirl belong
to the format reg2i16, but the sequence of oprand is different for the
instruction jirl. So adjust the parameter order of emit_jirl() to make
it more readable correspond with the Instruction Set Architecture manual.
Here are the instruction formats:
beq rj, rd, offs16
bne rj, rd, offs16
blt rj, rd, offs16
bge rj, rd, offs16
bltu rj, rd, offs16
bgeu rj, rd, offs16
jirl rd, rj, offs16
