[CodeGen] Fix PrologEpilogInserter to avoid duplicate allocation of SEH structs
Summary:
When stack-protection is activated and WinEH exceptions is used,
the EHRegNode (exception handling registration) is allocated twice on the stack.
This was not breaking anything except loosing space on the stack.
```
D:\src\llvm\examples>llc exc2.ll -debug-only=pei
alloc FI(0) at SP[-24]
alloc FI(1) at SP[-48] <<-- Allocated
alloc FI(1) at SP[-72] <<-- Allocated twice!?
alloc FI(2) at SP[-76]
alloc FI(4) at SP[-80]
alloc FI(3) at SP[-84]
```
