Quentin Colombet 4cf56917ea [X86] Do not run shrink-wrapping on function with split-stack attribute or HiPE 
calling convention.
The implementation of the related callbacks in the x86 backend for such
functions are not ready to deal with a prologue block that is not the entry
block of the function.

This fixes PR26107, but the longer term solution would be to fix those callbacks.

Quentin Colombet 5d2f7cfd44 [X86] Enable shrink-wrapping by default, but keep it disabled for stack frames 
without a frame pointer when unwind may happen.
This is a workaround for a bug in the way we emit the CFI directives for
frameless unwind information. See PR25614.
