Rollup merge of #47453 - pftbest:nointas, r=alexcrichton

Fix no_integrated_as option to work with new codegen architecture.

Old implementation called the assembler once per crate, but we need to call
it for each object file instead, because a single crate can now have more
than one object file.

This patch fixes issue #45836 (Can't compile core for msp430 in release mode)

This change can be tested on x86_64 using
```sh
export RUSTFLAGS="-C no_integrated_as -C save_temps"
```
