2a82d82936 Replace a use of ConstantUniqueMap for CAZ constants with a simple DenseMap. 
Now that the type system rewrite has landed, there is no need for its
complexity and std::map'ness.

7908480e4c An option to selectively enable parts of ARM EHABI support. 
This change adds an new value to the --arm-enable-ehabi option that
disables emitting unwinding descriptors. This mode gives a working
backtrace() without the (currently broken) exception support.

37abc488a0 Make Value::isDereferenceablePointer() handle unreachable code blocks. (This 
returns false in the event the computation feeding into the pointer is
unreachable, which maybe ought to be true -- but this is at least consistent
with undef->isDereferenceablePointer().) Fixes PR11825!

24973c1063 Basic runtime dynamic loading capabilities added to ELFObjectFile, implemented 
in a subclass named DyldELFObject. This class supports rebasing the object file
it represents by re-mapping section addresses to the actual memory addresses
the object was placed in. This is required for MC-JIT implementation on ELF with
debugging support.

Patch reviewed on llvm-commits.

Developed together with Ashok Thirumurthi and Andrew Kaylor.

69c96d71dd Help GCC along with code that's actually unreachable. 
Unfortunately I don't think there's a fix for this that will work upstream and
also satisfy Clang's -Wunreachable-code, which is a pity. But I'll give it some
more thought -perhaps there's some way out.

8c47ad8c47 Handle register masks in LiveVariables. 
A register mask operand kills any live physreg that isn't preserved.
Unlike an implicit-def operand, the clobbered physregs are never live
afterwards.

This means LiveVariables has to track a much smaller number of live
physregs, and it should spend much less time in addRegisterDead().

51222d1551 NEON use vmov.i32 to splat some f32 values into vectors. 
For bit patterns that aren't representable using the 8-bit floating point
representation for vmov.f32, but are representable via vmov.i32, treat
the .f32 syntax as an alias. Most importantly, this covers the case
'vmov.f32 Vd, #0.0'.
