LoongArch: Add support for TLS descriptors.

Browse source 
Add support for TLS descriptors on normal code model and extreme
code model.

Normal code model instruction sequence:
  -mno-explicit-relocs:
    la.tls.desc	$r4, s
    add.d	$r12, $r4, $r2
  -mexplicit-relocs:
    pcalau12i	$r4,%desc_pc_hi20(s)
    addi.d	$r4,$r4,%desc_pc_lo12(s)
    ld.d	$r1,$r4,%desc_ld(s)
    jirl	$r1,$r1,%desc_call(s)
    add.d	$r12, $r4, $r2

Extreme code model instruction sequence:
  -mno-explicit-relocs:
    la.tls.desc	$r4, $r12, s
    add.d	$r12, $r4, $r2
  -mexplicit-relocs:
    pcalau12i	$r4,%desc_pc_hi20(s)
    addi.d	$r12,$r0,%desc_pc_lo12(s)
    lu32i.d	$r12,%desc64_pc_lo20(s)
    lu52i.d	$r12,$r12,%desc64_pc_hi12(s)
    add.d	$r4,$r4,$r12
    ld.d	$r1,$r4,%desc_ld(s)
    jirl	$r1,$r1,%desc_call(s)
    add.d	$r12, $r4, $r2

The default is still traditional TLS model, but can be configured with
--with-tls={trad,desc}. The default can change to TLS descriptors once
libc and LLVM support this.

gcc/ChangeLog:

	* config.gcc: Add --with-tls option to change TLS flavor.
	* config/loongarch/genopts/loongarch.opt.in: Add -mtls-dialect to
	configure TLS flavor.
	* config/loongarch/loongarch-def.h (struct loongarch_target): Add
	tls_dialect.
	* config/loongarch/loongarch-driver.cc (la_driver_init): Add tls
	flavor.
	* config/loongarch/loongarch-opts.cc (loongarch_init_target): Add
	tls_dialect.
	(loongarch_config_target): Ditto.
	(loongarch_update_gcc_opt_status): Ditto.
	* config/loongarch/loongarch-opts.h (loongarch_init_target): Ditto.
	(TARGET_TLS_DESC): New define.
	* config/loongarch/loongarch.cc (loongarch_symbol_insns): Add TLS
	DESC instructions sequence length.
	(loongarch_legitimize_tls_address): New TLS DESC instruction sequence.
	(loongarch_option_override_internal): Add la_opt_tls_dialect.
	(loongarch_option_restore): Add la_target.tls_dialect.
	* config/loongarch/loongarch.md (@got_load_tls_desc<mode>): Normal
	code model for TLS DESC.
	(got_load_tls_desc_off64): Extreme cmode model for TLS DESC.
	* config/loongarch/loongarch.opt: Regenerate.
	* config/loongarch/loongarch.opt.urls: Ditto.
	* doc/invoke.texi: Add a description of the compilation option
	'-mtls-dialect={trad,desc}'.
