The replacement doesn't work for llc, but it is needed by
patchable-function-entry.ll.

This reverts commit aa9a30b83a.

Sam Elliott d57de491be [RISCV] Support llvm-objdump -M no-aliases and -M numeric
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`.

Ana Pazos 10de234905 [RISC-V] Fixed alias for addi x2, x2, 0
A missing check for non-zero immediate in MCOperandPredicate
caused c.addi16sp sp, 0 to be selected which is not a valid
instruction.

Alex Bradbury 6a4b5441e4 [RISCV] AsmParser support for the li pseudo instruction
The implementation follows the MIPS backend and expands the pseudo instruction 
directly during asm parsing. As the result, only real MC instructions are 
emitted to the MCStreamer. The actual expansion to real instructions is 
similar to the expansion performed by the GNU Assembler.

This patch supersedes D41949.
