Alex Bradbury 79d2b50ca8 [RISCV] Add InstAlias definitions for fgt.{s|d}, fge.{s|d}
These are produced by GCC and supported by GAS, but not currently contained in 
the pseudoinstruction listing in the RISC-V ISA manual.

Alex Bradbury 59136ffab1 [RISCV] Enable emission of alias instructions by default
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.
(see D40902 for context)

Alex Bradbury fa7e4ec837 [RISCV] Implement floating point assembler pseudo instructions
Adds the assembler aliases for the floating point instructions
which can be mapped to a single canonical instruction. The missing
pseudo instructions (flw, fld, fsw, fsd) are marked as TODO. Other
things, like for example PCREL_LO, have to be implemented first.

This patch builds upon D40902.
