This patch switches the default for `-riscv-no-aliases` to false
and updates all affected MC and CodeGen tests. As recommended in
https://reviews.llvm.org/D41071, MC tests use the canonical instructions and the CodeGen
tests use the aliases.

Additionally, for the f and d instructions with rounding mode,
the tests for the aliased versions are moved and tightened such
that they can actually detect if alias emission is enabled.
(see https://reviews.llvm.org/D40902 for context)
