[WASM] Fix overflow when reading custom section When reading a custom WASM section, it was possible that its name extended beyond the size of the section. This resulted in a bogus value for the section size due to the size overflowing. Fixes heap buffer overflow detected by OSS-fuzz: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=8190 Differential revision: https://reviews.llvm.org/D50387 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@339269 91177308-0d34-0410-b5e6-96231b3b80d8
