[RFC PATCH 1/2] RISC-V: __builtin_riscv_pause for all environment

From: Tsukasa OI The "pause" RISC-V hint instruction requires the 'Zihintpause' extension (in the assembler). However, GCC emits "pause" unconditionally, making an assembler error while compiling code with __builtin_riscv_pause while the 'Zihintpause' extension disabled. However, the "pause" in
