[X86] add dwarf information for loop stack probe
This patch is based on https://reviews.llvm.org/D99585.
While inside the stack probing loop, temporarily change the CFA
to be based on r11/eax, which are already used to hold the loop bound.
The stack pointer cannot be used for CFI here as it changes during the loop,
so it does not have a constant offset to the CFA.
