From: Zhongyao Chen <chen.zhong...@zte.com.cn>
users can now write code like the following to adapt to the
current RISC-V profile selected at compile time:
```c
#ifdef __riscv_rva23u64
// Code specific to the rva23u64 profile
#endif
```
Changes since v1:
add testcases
gcc/
* common/config/riscv/riscv-common.cc
(riscv_subset_list::get_profile_name):
New function.
* config/riscv/riscv-c.cc (riscv_cpu_cpp_builtins): Define
profile macro if a profile is detected.
* config/riscv/riscv-subset.h (riscv_subset_list::get_profile_name):
Declare.
gcc/testsuite/
* gcc.target/riscv/predef-profiles-1.c: New test for __riscv_rvi20u64.
* gcc.target/riscv/predef-profiles-2.c: New test for __riscv_rvi20u32.
* gcc.target/riscv/predef-profiles-3.c: New test for __riscv_rva20u64.
* gcc.target/riscv/predef-profiles-4.c: New test for __riscv_rva22u64.
* gcc.target/riscv/predef-profiles-5.c: New test for __riscv_rva23u64.
* gcc.target/riscv/predef-profiles-6.c: New test for __riscv_rva23s64.
* gcc.target/riscv/predef-profiles-7.c: New test for __riscv_rvb23u64.
* gcc.target/riscv/predef-profiles-8.c: New test for __riscv_rvb23s64.
