LoongArch: Fix an ODR violation
When bootstrapping GCC 14 with --with-build-config=bootstrap-lto, an ODR
violation is detected:
../../gcc/config/loongarch/loongarch-opts.cc:57: warning:
'abi_minimal_isa' violates the C++ One Definition Rule [-Wodr]
57 | abi_minimal_isa[N_ABI_BASE_TYPES][N_ABI_EXT_TYPES];
../../gcc/config/loongarch/loongarch-def.cc:186: note:
'abi_minimal_isa' was previously declared here
186 | abi_minimal_isa = array<array<loongarch_isa, N_ABI_EXT_TYPES>,
../../gcc/config/loongarch/loongarch-def.cc:186: note:
code may be misoptimized unless '-fno-strict-aliasing' is used
Fix it by adding a proper declaration of abi_minimal_isa into
loongarch-def.h and remove the ODR-violating local declaration in
loongarch-opts.cc.
gcc/ChangeLog:
* config/loongarch/loongarch-def.h (abi_minimal_isa): Declare.
* config/loongarch/loongarch-opts.cc (abi_minimal_isa): Remove
the ODR-violating locale declaration.
