fc0d7400bc Put back the initializing the targets in the disassembler API with a comment as 
to why this is needed.  This broke the darwin's otool(1) program.  This change
was made in r144385.

d9f0ff56a1 Transfer regmasks to MRI. 
MRI keeps track of which physregs have been used. Make sure it gets
updated with all the regmask-clobbered registers.

Delete the closePhysRegsUsed() function which isn't necessary.

dbe266be35 Calls and invokes with the new clang.arc.no_objc_arc_exceptions 
metadata may still unwind, but only in ways that the ARC
optimizer doesn't need to consider. This permits more
aggressive optimization.

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.

actually work, at least as described. LLVM Metadata is not
intended to suppress LLVM IR rules, as it can be stripped at
any time.

0f7de3542f Revert r150288, "Allow Post-RA LICM to hoist reserved register reads." 
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... 
Thanks to Anton, Duncan and Rafael for helping me track this down.
Pointy hat to Rafael for introducing the bug in the first place.

81266c5c93 Add support for invariant.start inside the static constructor evaluator. This is 
useful to represent a variable that is const in the source but can't be constant
in the IR because of a non-trivial constructor. If globalopt evaluates the
constructor, and there was an invariant.start with no matching invariant.end
possible, it will mark the global constant afterwards.

8b0a3f2df9 Remove the YMM_HI_6_15 hack. 
Call clobbers are now represented with register mask operands.  The
regmask can easily represent the fact that xmm6 is call-preserved while
ymm6 isn't.  This is automatically computed by TableGen from the
CalleeSavedRegs containing xmm6.
