This patch sets correct encodings for DWARF exception handling for RISC-V (other than call site encoding, which must be udata4 rather than uleb128 and is handled by D63415). This has the same intend as D63409, except this version matches GCC/binutils behaviour which uses the same encodings regardless of PIC/non-PIC and medlow/medany code model. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@366327 91177308-0d34-0410-b5e6-96231b3b80d8
