know that this is a library function. autoconf depends on this

This matters in assembler mode, where this is silently allowed.
This fixes rdar://6709206.

Model inline asm constraint which ties an input to an output register as machine operand TIED_TO constraint. This eliminated the need to pre-allocate registers for these. This also allows register allocator can eliminate the unneeded copies.

Do not fold away subreg_to_reg if the source register has a sub-register index. That means the source register is taking a sub-register of a larger register. e.g. On x86
%RAX<def> = ...
%RAX<def> = SUBREG_TO_REG 0, %EAX:3<kill>, 3
The first def is defining RAX, not EAX so the top bits were not zero-extended.

Recognize rvalue references in C++03, but complain about them. This leads to far better error recovery.

incompatibilities in assignments from other pointer incompatibilities.  
Based off of the patch in PR3342.  (This doesn't implement -Wno-pointer-sign,
but I don't know the driver code very well.)
