RISC-V: make USE_LOAD_ADDRESS_MACRO easier to understand
The current macro has several && and || making it really hard to understand
the first time.
Signed-off-by: Vineet Gupta <vineetg@rivosinc.com>
gcc/ChangeLog:
* config/riscv/riscv.h (LOCAL_SYM_P): New.
(USE_LOAD_ADDRESS_MACRO): Simplify by calling LOCAL_SYM_P.
