Preserve the dis34 output on a failed round-trip instead of claiming a
deleted temp file is kept, require GSPA "No Warnings" in addition to
"No Errors", and correct the six-function and M1 pipeline comments.
Raw clang IR has byte GEP offsets that llc treats as bits, so addresses
are 8x too small; always run tms-clang/tms-bitaddr --scale first.
Document that M1 supports only zero-initialized globals and rejects
.data/string literals loudly, and defer the spec's .data initializer
probe to M2.
--normalize lowers GEP offsets as already-scaled bit offsets. A typed
GEP still carries a DataLayout byte offset and a vector GEP has no
scalar lowering, so accepting either produced addresses 8x too small.
Check all instruction and constant-expression GEPs and fail clearly;
--scale still scales typed GEPs normally. Add positive and negative
tool tests.
