Graeme Geldenhuys c9dde987f0 vendor: update QBE from v1.2 to v1.3
QBE 1.3 (released 2026-06-01) adds Windows AMD64 ABI support
(amd64_win target), improved PIC via extern symbol constants,
GVN/GCM optimisation passes, if-conversion, and various
correctness and performance fixes.

All 2293 compiler tests pass against the new QBE binary.

There is an experimental amd64_win (native Windows ABI and calling
convention).
In tree, this is currently only tested via cross-compilation from a
Linux host, and using wine to run the tests.
You'll need something like:
sudo apt install mingw64-w64 dos2unix wine
and then
make check-amd64_win
should pass.
