[IROutliner] Removing a duplicate addition, causing overestimates in IROutliner.
There was an extra addition left over from a previous commit for the
cost model, this removes it.

[IROutliner] Adding a cost model, and debug option to turn the model off.
This adds a cost model that takes into account the total number of
machine instructions to be removed from each region, the number of
instructions added by adding a new function with a set of instructions,
and the instructions added by handling arguments.

[IROutliner] Adding support for elevating constants that are not the same in each region to arguments
When there are constants that have the same structural location, but not
the same value, between different regions, we cannot simply outline the
region. Instead, we find the constants that are not the same in each
location, and promote them to arguments to be passed into the respective
functions. At each call site, we pass the constant in as an argument
regardless of type.

[IROutliner] Deduplicating functions that only require inputs.
Extracted regions can have both inputs and outputs. In addition, the
CodeExtractor removes inputs that are only used in llvm.assumes, and
sunken allocas (values are used entirely in the extracted region as
denoted by lifetime intrinsics). We also cannot combine sections that
have different constants in the same structural location, and these
constants will have to elevated to argument. This patch deduplicates
extracted functions that only have inputs and non of the special cases.
We test that correctly deduplicate in:

Extracted regions can have both inputs and outputs. In addition, the
CodeExtractor removes inputs that are only used in llvm.assumes, and
sunken allocas (values are used entirely in the extracted region as

have different constants in the same structural location, and these

extracted regions to those that only require inputs, and do not have any
