Lewis Revill aa79a3fe8e [RISCV] Support assembling TLS add and associated modifiers
This patch adds support in the MC layer for parsing and assembling the
4-operand add instruction needed for TLS addressing. This also involves
parsing the %tprel_hi, %tprel_lo and %tprel_add operand modifiers.

Kito Cheng 303217e8b4 [RISCV] Implement pseudo instructions for load/store from a symbol address.
Summary:
Those pseudo-instructions are making load/store instructions able to
load/store from/to a symbol, and its always using PC-relative addressing
to generating a symbol address.

Alex Bradbury 7d0e18d0dd [RISCV][MC] Reject bare symbols for the simm12 operand type
addi a0, a0, foo and lw a0, foo(a0) and similar are now rejected. An explicit 
%lo and %pcrel_lo modifier is required. This matches gas behaviour.

Alex Bradbury 7bc2a95bb9 [RISCV] MC layer support for the standard RV32D instruction set extension
As the FPR32 and FPR64 registers have the same names, use 
validateTargetOperandClass in RISCVAsmParser to coerce a parsed FPR32 to an 
FPR64 when necessary. The rest of this patch is very similar to the RV32F 
patch.
