This patch supports the R_RISCV_JAL relocation. Moreover, it will fix the extractBits function's behavior as it extracts Size + 1 bits. In the test ELF_jal.s: Before: ``` Hi: 4294836480 extractBits(Hi, 12, 8): 480 ``` After: ``` Hi: 4294836480 extractBits(Hi, 12, 8): 224 ``` Reviewed By: StephenFan Differential Revision: https://reviews.llvm.org/D117975
