Alex Bradbury 71f45455e1 [RISCV] Add the RISCV target and compiler driver 
As RV64 codegen has not yet been upstreamed into LLVM, we focus on RV32 driver 
support (RV64 to follow).

Nemanja Ivanovic e96e697294 [PowerPC] Enable -fomit-frame-pointer by default for PPC 
As is the case on platforms like Mips, X86 and SystemZ, the -fomit-frame-pointer
should be enabled by default on PPC when optimizing at -O1 and above. This
brings the behaviour of LLVM on PPC in line with GCC.

Rafael Espindola 224dd63fff Don't use the frame pointer on linux x86 and x86_64 if optimizing. This 
matches gcc's behavior.

Fixes PR8186.
