[MTE] Pin the tagged base pointer to one of the stack slots.
Summary:
Pin the tagged base pointer to one of the stack slots, and (if
necessary) rewrite tag offsets so that an object that occupies that
slot has both address and tag offsets of 0. This allows ADDG
instructions for that object to be eliminated and their uses replaced
with the tagged base pointer itself.
This optimization must be done in machine instructions and not in the IR
instrumentation pass, because referring to a stack slot through an IRG
pointer would confuse the stack coloring pass.
The optimization makes a (pretty naive) attempt to find the slot that
would benefit the most by counting the uses of stack slots in the
function.

MemTag: unchecked load/store optimization.
Summary:
MTE allows memory access to bypass tag check iff the address argument
is [SP, #imm]. This change takes advantage of this to demote uses of
tagged addresses to regular FrameIndex operands, reducing register
pressure in large functions.
MO_TAGGED target flag is used to signal that the FrameIndex operand
refers to memory that might be tagged, and needs to be handled with
care. Such operand must be lowered to [SP, #imm] directly, without a
scratch register.
The transformation pass attempts to predict when the offset will be
out of range and disable the optimization.
AArch64RegisterInfo::eliminateFrameIndex has an escape hatch in case
this prediction has been wrong, but it is quite inefficient and should
be avoided.
