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.

add a fastpath to ConstantExpr::getBitCast to handle the case when an obviously
...
unneeded bitcast is requested. This is common for frontends who just unconditionally
cast even if the target is often the right type already. THis prevents going into
getFoldedCast which switches on the opcode and does a bunch of other stuff before
doing the same opzn.
