David Green	cd76f43b49	[ARM] Set the immediate cost of GEP operands to 0 This prevents constant gep operands from being hoisted by the Constant Hoisting pass, leaving them to CodegenPrepare which can usually do a better job at splitting large offsets. This can, in general, improve performance and decrease codesize, especially for v6m where many constants have a high cost.

[ARM] Set the immediate cost of GEP operands to 0

This prevents constant gep operands from being hoisted by the Constant
Hoisting pass, leaving them to CodegenPrepare which can usually do a
better job at splitting large offsets. This can, in general, improve
performance and decrease codesize, especially for v6m where many
constants have a high cost.
