early-remat.c: Fix new/delete mismatch [PR100230]
This simple patch fixes a mistmatched operator new/delete in
early-remat.c which triggers ASan errors on (at least) AArch64 when
compiling SVE code.
gcc/ChangeLog:
PR rtl-optimization/100230
* early-remat.c (early_remat::sort_candidates): Use delete[]
instead of delete for array allocated with new[].
(cherry picked from commit 5d87c2251c441f056e0a44f928ffcb8a8a679b6b)
