[PATCH] early-remat.c: Fix new/delete mismatch [PR100230]

[Alex Coplan via Gcc-patches]

Hi,

This simple patch fixes a mismatched operator new/delete in
early-remat.c which triggers ASan errors on (at least) AArch64 when
compiling SVE code.

Bootstrap and regtest on aarch64-linux-gnu in progress.

OK for trunk and backports (as appropriate) if testing looks good?

Thanks,
Alex
