ef4c80e07b Don't skip debug instructions when looking for the insertion point of 
the cast. If we do, we can end up with

   inst1
   ---------------  < Insertion point
   dbg inst
   new inst

instead of the desired

   inst1
   new inst
   ---------------  < Insertion point
   dbg inst

Another option would be for InsertNoopCastOfTo (or its callers) to move the
insertion point and we would end up with

   inst1
   dbg inst
   new inst
   ---------------  < Insertion point

but that complicates the callers. This fixes PR12018 (and firefox's build).

3dc7c5138d Refactor 'handleMove' code in live intervals. Clients of LiveIntervals won't see 
any changes.

Internally this adds a private inner class HMEditor, to LiveIntervals. HMEditor provides
an API for updating live intervals when code is moved or bundled.

This caused miscompilations on out-of-tree targets, and possibly i386 as
well.

I'll find some other way of hoisting %rip-relative loads from loops
containing calls.

637b25a6a0 Don't lazily allocate eh_frame. We're not lazily allocating things like the LSDA, which are only used when the eh frame is used, so this lazy allocation doesn't really make sense. 
Fix the type of eh_frame on Solaris so that Sun ld doesn't fail to combine them (thus making it impossible for the unwind library to find them and breaking exceptions).

ca5b752d18 It turns out that putting an 8-byte symbol in a 4-byte section makes Solaris ld sulk. GNU ld is perfectly happy with it, which is worrying for a whole other set of reasons...

Pointy hat to Rafael for introducing the bug in the first place.
