[RISCV] Just reporting an error shouldn't generate a crash diagnostic (#134040)

Wanting to examine some of generated code, I tried MCA with the command:
~~~bash
llvm-mca -mtriple=riscv32-unknown-unknown -mcpu=rocket -iterations=300
core_list_join.s
~~~
I was greeted with the following error message:
~~~
LLVM ERROR: RV32 target requires an RV32 CPU
PLEASE submit a bug report to
https://github.com/llvm/llvm-project/issues/ and include the crash
backtrace.
Stack dump:

On beginning to investigate the “bug”, I discovered that the code was
simply attempting to report a user error. It used report_fatal_error()
to do so but with the “bool GenCrashDiag” argument enabled (the
default). This tiny change adds a wrapper function which calls
report_fatal_error() as before but with GenCrashDiag disabled.
