%highest(sym1 - sym2 + const) relocations. Remove "ABS_" from VK_Mips_HI and VK_Mips_LO enums in MipsMCExpr, to be consistent with VK_Mips_HIGHER and VK_Mips_HIGHEST. This change also deletes test file test/MC/Mips/higher_highest.ll and moves its CHECK's to the new test file test/MC/Mips/higher-highest-addressing.s. The deleted file tests that R_MIPS_HIGHER and R_MIPS_HIGHEST relocations are emitted in the .o file. Since it uses -force-mips-long-branch option, it was created when MipsLongBranch's implementation was emitting R_MIPS_HIGHER and R_MIPS_HIGHEST relocations in the .o file. It was disabled when MipsLongBranch started to directly calculate offsets.
