Represents the cost of inlining a function.
This supports special values for functions which should "always" or "never" be inlined. Otherwise, the cost represents a unitless amount; smaller values increase the likelihood of the function being inlined.
Objects of this type also provide the adjusted threshold for inlining based on the information available for a particular callsite. They can be directly tested to determine if inlining should occur given the cost and threshold for this cost metric.

Get the inline cost estimate.
It is an error to call this on an "always" or "never" InlineCost.

inline |
Get the cost delta from the threshold for inlining.
Only valid if the cost is of the variable kind. Returns a negative value if the cost is too high to inline.
