Reid Kleckner fc2be394ef [WinEH] Emit prologues and epilogues for funclets ... Summary: 32-bit funclets have short prologues that allocate enough stack for the largest call in the whole function. The runtime saves CSRs for the funclet. It doesn't restore CSRs after we finally transfer control back to the parent funciton via a CATCHRET, but that's a separate issue. 32-bit funclets also have to adjust the incoming EBP value, which is what llvm.x86.seh.recoverframe does in the old model. 64-bit funclets need to spill CSRs as normal. For simplicity, this just spills the same set of CSRs as the parent function, rather than trying to compute different CSR sets for the parent function and each funclet. 64-bit funclets also allocate enough stack space for the largest outgoing call frame, like 32-bit.
