50918fa8f0 missed a use of SizeRequired.

a1dcdf0bd4 eliminate the TargetInstrInfo::GetInstSizeInBytes hook. 
ARM/PPC/MSP430-specific code (which are the only targets that
implement the hook) can directly reference their target-specific
instrinfo classes.

7c16f1a16e remove the dwarf sizing stuff which is now dead, it was 
"yet another" copy of the dwarf EH emission code that was
copied, pasted and slightly hacked up.

9c30949ae1 switch a private implementation of GetFunctionSizeInBytes. 
This is probably not the best way to implement "Force LR to 
be spilled if the Thumb function size is > 2048." do this, 
it should use the branch shortening infrastructure, but I'm
just preserving functionality here.

367aa754b1 instead of migrating it to the MC instruction encoder, just 
rip out the implementation of X86InstrInfo::GetInstSizeInBytes.
The code being ripped out just implemented a copy and hacked up
version of the (old) instruction encoder, and is buggy and 
terrible in other ways.  Since "GetInstSizeInBytes" is really 
only there to support the JIT's "NeedsExactSize" hook (which
noone is using), just rip out the code.  I will rip out the
NeedsExactSize hook next.

This resolves rdar://7617809 - switch X86InstrInfo::GetInstSizeInBytes to use X86MCCodeEmitter

604a50cd71 Add new RegionInfo pass. 
The RegionInfo pass detects single entry single exit regions in a function,
where a region is defined as any subgraph that is connected to the remaining
graph at only two spots.
Furthermore an hierarchical region tree is built.
Use it by calling "opt -regions analyze" or "opt -view-regions".

32f6aba7d8 Fix constant island pass's handling of tBR_JTr. The offset of the instruction does not have to be 4-byte aligned. Rather, it's the offset + 2 that must be aligned since the instruction expands into: 
mov     pc, r1
        .align  2
LJTI0_0_0:
        .long    LBB0_14

This fixes rdar://8213383. No test case since it's not possible to come up with a suitable small one.
