d589099eec make the asmparser reject function and type redefinitions. 'Merging' hasn't been 
needed since llvm-gcc 3.4 days.

7a1b9bdd2b Remove support for using "foo" as symbols instead of %"foo". This is ancient 
syntax and has been long obsolete.  As usual, updating the tests is the nasty

b712ef9569 Allocate SystemZ callee-saved registers backwards: R13-R6 
The reserved R14-R15 are always saved in the prolog, and using CSRs
starting from R13 allows them to be saved in one instruction.

Thanks to Anton for explaining this.

f3a789d931 Remove old backwards compatibility support from the parser for autoupgrading 
the old malloc/free instructions, and for 'sext' and 'zext' as function 
attributes (they are spelled signext/zeroext now), and support for result
value attributes being specified after a function.

Additionally, diagnose invalid attributes on functions with an error message
instead of an abort in the verifier.

dd5a847152 Rename TRI::getAllocationOrder() to getRawAllocationOrder(). 
Also switch the return type to ArrayRef<unsigned> which works out nicely
for ARM's implementation of this function because of the clever ArrayRef
constructors.

The name change indicates that the returned allocation order may contain
reserved registers as has been the case for a while.

c02a6fa7d8 Don't use register classes larger than TLI->getRegClassFor(VT). 
In Thumb mode we cannot handle GPR virtual registers, even though some
instructions can. When isel is lowering a CopyFromReg, it should limit
itself to subclasses of getRegClassFor(VT).

714c0eb811 Move PBQP off allocation_order_begin. No functional change intended. 
I think PBQP could use RegisterClassInfo, but it didn't fit neatly with
the external interfaces that PBQP uses, so I'll leave that to Lang.

1300f3019e Change the REG_SEQUENCE SDNode to take an explict register class ID as its first operand. This operand is lowered away by the time we reach MachineInstrs, so the actual register-allocation handling of them doesn't need to change. 
This is intended to support using REG_SEQUENCE SDNode's with type MVT::untyped, and is part of the long road to eliminating some of the hacks we currently use to support register pairs and other strange constraints, particularly on ARM NEON.

79c890f64f Add TargetRegisterInfo::getRawAllocationOrder(). 
This virtual function will replace allocation_order_begin/end as the one
to override when implementing custom allocation orders. It is simpler to
have one function return an ArrayRef than having two virtual functions
computing different ends of the same array.

Use getRawAllocationOrder() in place of allocation_order_begin() where
it makes sense, but leave some clients that look like they really want
the filtered allocation orders from RegisterClassInfo.
