  Changed paths:
    M clang/lib/Driver/ToolChains/Arch/RISCV.cpp
    M clang/test/Driver/riscv-default-features.c
    M clang/test/Driver/riscv-features.c

  Log Message:
  [RISCV] Don't add -unaligned-scalar-mem to target features by default.

Only pass it +unaligned-scalar-mem/-unaligned-scalar-mem if the
user has passed one of the alignment options.

This allows us to add unaligned-scalar-mem as a feature on CPUs
that support it.
