[X86] Remove encoding information from the TAILJMP instructions that are lowered by MCInstLowering. Fix LowerPATCHABLE_TAIL_CALL to also convert them to regular JMP/JCC instructions
There are 5 instructions here that are converted from TAILJMP opcodes to regular JMP/JCC opcodes during MCInstLowering. So normally there encoding information isn't used. The exception being when XRay wraps them in PATCHABLE_TAIL_CALL.
For the ones that weren't already handled in MCInstLowering, add handling for those and remove their encoding information.
This patch fixes PATCHABLE_TAIL_CALL to do the same opcode conversion as the regular lowering patch. Then removes the encoding information.
