This option lets you set the default threshold for inlining a function. It
takes an unsigned integer as a value. Inlining is based on a cost model, where
a higher threshold will allow more inlining.
The default depends on the [opt-level](#opt-level). Current values are between
25 to 275.
The default depends on the [opt-level](#opt-level):
| opt-level | Threshold |
|-----------|-----------|
| 0 | N/A, only inlines always-inline functions |
| 1 | N/A, only inlines always-inline functions and LLVM lifetime intrinsics |
| 2 | 225 |
| 3 | 275 |
