[win][x64] Re-use fixed object if multiple catchpads use the same alloca for their catch objects (#147849)
Addresses
<https://github.com/llvm/llvm-project/pull/147421#discussion_r2191234968>
for x86
If more than one `catchpad ` uses the same `alloca` for their catch
objects, then we will allocate more than one object in the fixed area
resulting in wasted stack space.
As a follow up, Clang could be updated to re-use the same `alloca` for
all by-reference and by-pointer catch objects.
