Add declare_object_symbol_alias for assembly codes (BZ #28128)
There are 2 problems in:
#define declare_symbol_alias(symbol, original, type, size) \
declare_symbol_alias_1 (symbol, original, type, size)
#ifdef __ASSEMBLER__
# define declare_symbol_alias_1(symbol, original, type, size) \
strong_alias (original, symbol); \
.type C_SYMBOL_NAME (symbol), %##type; \
.size C_SYMBOL_NAME (symbol), size
1. .type and .size are substituted by arguments.
2. %##type is expanded to "% type" due to the GCC bug:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101613
But assembler doesn't support "% type".
Workaround BZ #28128 by
1. Don't define declare_symbol_alias for assembly codes.
2. Define declare_object_symbol_alias for assembly codes.
