Fixed error detected by msan. The size field of the .ARM.exidx synthetic section needs to be initialized to at least estimation level before calling assignAddresses as that will use the size field. This was previously reverted in 1ca16fc4f5146b90512d4740cfcc4d4c34640853. Differential Revision: https://reviews.llvm.org/D78422
