c34ad45992 target/loongarch: Fix the CSRRD CPUID instruction on big endian hosts
The test in tests/avocado/machine_loongarch.py is currently failing
on big endian hosts like s390x. By comparing the traces between running
the QEMU_EFI.fd bios on a s390x and on a x86 host, it's quickly obvious
that the CSRRD instruction for the CPUID is behaving differently. And
indeed: The code currently does a long read (i.e. 64 bit) from the
address that points to the CPUState->cpu_index field (with tcg_gen_ld_tl()
in the trans_csrrd() function). But this cpu_index field is only an "int"
(i.e. 32 bit). While this dirty pointer magic works on little endian hosts,
it of course fails on big endian hosts. Fix it by using a proper helper
function instead.

target/loongarch: Fix the vinsgr2vr/vpickve2gr instructions cause system coredump
The vinsgr2vr/vpickve2gr instructions need use get_src/get_dst to get
gpr registers value, not cpu_gpr[]. The $zero register does not
have cpu_gpr[0] allocated.

60a7e25ea2 target/loongarch: Drop temp_new
Translators are no longer required to free tcg temporaries,
therefore there's no need to record temps for later freeing.
Replace the few uses with tcg_temp_new.

c2b618a8c1 target/loongarch: Disassemble jirl properly
While jirl shares the same instruction format as bne etc,
it is not assembled the same.  In particular, rd is printed
first not second and the immediate is not pc-relative.

Decode into the arg_rr_i structure, which prints correctly.
This changes the "offs" member to "imm", to update translate.
