fix clobbered or lateout registers overlapping with input registers

[folkertdev]

Apparently, in GCC, input registers cannot also be clobbered.

this previously errored https://godbolt.org/

this fixes half of tests/ui/asm/x86_64/multiple-clobber-abi.rs, but it also runs into #451

Looks good to me.
There are possibly two things to change.

this fixes half of tests/ui/asm/x86_64/multiple-clobber-abi.rs, but it also runs into #451

I implemented the ABIs used in this test in #629, so rebasing should allow this test to pass.

[folkertdev]

locally I can't quite get that to work, but maybe something else needs to be updated?

---- [ui] tests/ui/asm/x86_64/multiple-clobber-abi.rs stdout ----
Saved the actual stderr to "/home/folkertdev/rust/rustc_codegen_gcc/build/rust/build/x86_64-unknown-linux-gnu/test/ui/asm/x86_64/multiple-clobber-abi/multiple-clobber-abi.stderr"
normalized stderr:
gcc_jit_function_add_attribute: attribute should be a `gcc_jit_fn_attribute` enum value
gcc_jit_function_add_attribute: attribute should be a `gcc_jit_fn_attribute` enum value

I did remove the line to see whether CI maybe did update correctly already.

edit: it likely just needs the master feature?

Oh, I forgot to update this file with the latest commit.
Do you use the default config.toml which downloads libgccjit.so?

[folkertdev]

I think so yes

[antoyo]

Could you please update the file with the latest commit from the gcc repo and see if this works?
If so, please add this change to this PR.

yes that does work, I've added it now.

[antoyo]

Is there any other change you would like to make or is this ready to merge?

[folkertdev]

no I think we're good

Thanks for your contribution!
