Dan Zheng bab23d8298 SILOptimizer: fix partial_apply optimization. (#31552) ...

`partial_apply` can be rewritten to `thin_to_thick_function` only if the
specialized callee is `@convention(thin)`.

This condition is newly exercised by the differentiation transform:
`{JVP,VJP}Emitter::visitApplyInst` generates argument-less `partial_apply`
with `@convention(method)` callees.

Resolves SR-12732.
