Workaround gcc 14.2.0-9 regression in no-tree-slp-vectorize on Graviton
gcc 14.2.0-9 causes vector instructions to be emitted in the constructor when it is being inlined into BaseHttpMethod::Loop(), which seemingly only on Graviton instances, causes the field to be initialized to 0 (Chunked) instead of 2 (Closes), causing the code to fail later when it tries to interpret file data as the chunk size. It's plausible we are missing some register saving here - that is, the q31 register overrides an x register. Work around this by making Closes element 0, such that 0 initialisation results in the correct Closes value. Reported-By: Myon on IRC
