In lld/test/wasm/custom-section-name.ll, it's because bulk-memory makes the target_features section bigger and thus changes some of the section offsets and it was easier to just disable bulk-memory than to figure out the new section offsets. I can update the section offsets if you prefer though.

In lld/test/wasm/data-segments.ll, it's because the test is written to test both bulk-memory and non-bulk-memory, and to keep it doing that, it's now necessary to explicitly disable bulk-memory for the non-bulk-memory case.

In lld/test/wasm/lto/stub-library-libcall.s it's because the test is testing the use of a memcpy stub function, and with bulk-memory it gets inlined.

llvm/test/MC/WebAssembly/extern-functype-intrinsic.ll is similarly testing memset calls.

llvm/test/MC/WebAssembly/libcall.ll is similarly testing memcpy calls.
