LoongArch: Subdivision symbol type, add SYMBOL_PCREL support.

1. Remove cModel type support other than normal.
2. The method for calling global functions changed from 'la.global + jirl' to 'bl'
   when complied add '-fplt'.

gcc/ChangeLog:

	* config/loongarch/constraints.md (a): Delete the constraint.
	(b): A constant call not local address.
	(h): Delete the constraint.
	(t): Delete the constraint.
	* config/loongarch/loongarch-opts.cc (loongarch_config_target):
	Remove cModel type support other than normal.
	* config/loongarch/loongarch-protos.h (enum loongarch_symbol_type):
	Add new symbol type 'SYMBOL_PCREL', 'SYMBOL_TLS_IE' and 'SYMBOL_TLS_LE'.
	(loongarch_split_symbol): Delete useless function declarations.
	(loongarch_split_symbol_type): Delete useless function declarations.
	* config/loongarch/loongarch.cc (enum loongarch_address_type):
	Delete unnecessary comment information.
	(loongarch_symbol_binds_local_p): Modified the judgment order of label
	and symbol.
	(loongarch_classify_symbol): Return symbol type. If symbol is a label,
	or symbol is a local symbol return SYMBOL_PCREL. If is a tls symbol,
	return SYMBOL_TLS. If is a not local symbol return SYMBOL_GOT_DISP.
	(loongarch_symbolic_constant_p): Add handling of 'SYMBOL_TLS_IE'
	'SYMBOL_TLS_LE' and 'SYMBOL_PCREL'.
	(loongarch_symbol_insns): Add handling of 'SYMBOL_TLS_IE' 'SYMBOL_TLS_LE'
	and 'SYMBOL_PCREL'.
	(loongarch_address_insns): Sort code.
	(loongarch_12bit_offset_address_p): Sort code.
	(loongarch_14bit_shifted_offset_address_p): Sort code.
	(loongarch_call_tls_get_addr): Sort code.
	(loongarch_legitimize_tls_address): Sort code.
	(loongarch_output_move): Remove schema support for cmodel other than normal.
	(loongarch_memmodel_needs_release_fence): Sort code.
	(loongarch_print_operand): Sort code.
	* config/loongarch/loongarch.h (LARCH_U12BIT_OFFSET_P):
	Rename to LARCH_12BIT_OFFSET_P.
	(LARCH_12BIT_OFFSET_P): New macro.
	* config/loongarch/loongarch.md: Reimplement the function call. Remove schema
	support for cmodel other than normal.
	* config/loongarch/predicates.md (is_const_call_weak_symbol): Delete this predicate.
	(is_const_call_plt_symbol): Delete this predicate.
	(is_const_call_global_noplt_symbol): Delete this predicate.
	(is_const_call_no_local_symbol): New predicate, determines whether it is a local
	symbol or label.

gcc/testsuite/ChangeLog:

	* gcc.target/loongarch/func-call-1.c: New test.
	* gcc.target/loongarch/func-call-2.c: New test.
	* gcc.target/loongarch/func-call-3.c: New test.
	* gcc.target/loongarch/func-call-4.c: New test.
