MIPSR6 introduced several new jump instructions and deprecated
the use of the 'j' instruction. For microMIPS32R6, 'j' was removed
entirely and it only has non delay slot jumps.

This patch adds support for MIPSR6 by using some https://reviews.llvm.org/source/compiler-rt/ instructions--
'bc' instead of 'j', 'jic $reg, 0' instead of 'jalr $zero, $reg'--
and modifies the sequences not to use delay slots for https://reviews.llvm.org/source/compiler-rt/.
