Summary:
Now that llvm-objdump allows target-specific options, we match the
`no-aliases` and `numeric` options for RISC-V, as supported by GNU objdump.
This is done by overriding the variables used for the command-line options, so
that the command-line options are still supported.
This patch updates all tests using `llvm-objdump -riscv-no-aliases` to use
`llvm-objdump -M no-aliases`.

This further improves compatibility with GNU as, allowing input such as the
following to be assembled:
.equ CONST, 0x123456
li a0, CONST
addi a0, a0, %lo(CONST)
.equ CONST, 1
slli a0, a0, CONST
Note that we don't have perfect compatibility with gas, as it will avoid
emitting a relocation in this case:
addi a0, a0, %lo(CONST2)
.equ CONST2, 0x123456
Thanks to Shiva Chen for suggesting a better way to approach this during review.

Standardise on check lines:
* CHECK-ASM
* CHECK-OBJ
* CHECK-ASM-AND-OBJ
This allows for the addition of tests involving symbol operands, which will
not result in identical instructions in both assembly and disassembled object
output.
This commit doesn't exploit this reworking to increase test coverage of symbol
operands - that will come in a future patch.

This patch switches the default for -riscv-no-aliases to false
and updates all affected MC and CodeGen tests. As recommended in
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.
