LoongArch: Disable explicit reloc for TLS LD/GD with -mexplicit-relocs=auto
Binutils 2.42 supports TLS LD/GD relaxation which requires the assembler
macro.
gcc/ChangeLog:
* config/loongarch/loongarch.cc (loongarch_explicit_relocs_p):
If la_opt_explicit_relocs is EXPLICIT_RELOCS_AUTO, return false
for SYMBOL_TLS_LDM and SYMBOL_TLS_GD.
(loongarch_call_tls_get_addr): Do not split symbols of
SYMBOL_TLS_LDM or SYMBOL_TLS_GD if la_opt_explicit_relocs is
EXPLICIT_RELOCS_AUTO.
gcc/testsuite/ChangeLog:
* gcc.target/loongarch/explicit-relocs-auto-tls-ld-gd.c: Check
for la.tls.ld and la.tls.gd.
