[PATCH] D18315: [mips] MIPSR6 Compact jump support

This patch adds support for compact jumps similiar to the previous compact
branch support for MIPSR6. Unlike compact branches, compact jumps do not
have a forbidden slot.

As MipsInstrInfo::getEquivalentCompactForm can determine the correct
expansion for jumps and branches for both microMIPS and MIPSR6, simplify
the delay slot filler when producing compact CTIs in cases where a delay slot
can be filled.
