Reed Kotler 0d409e2dfe Check in conditional branches for constant islands. Still need to finish 
conditional branches for very large targets. That will be the next small
patch. Everything now should in principle work as good (functionality
wise) as without constant islands so we decided at Mips/Imagination to
make constant islands the default for Mips16 now so that it will get
excercised a lot and this port is still experimentatl though hopefully soon
we will change the status. Some more cleanup and code review is in order
but things are converging fast.

Reed Kotler de64774b4d For Mips16, start to consolidate all forms of 32 bit literal loading so that 
they can be better handled and optimized in the Mips16 constant island code.
