Pull request description:

  Switching to using GCC 14.x for release builds has come up multiple times recently. It will eventually be needed for #25573, and could also be useful for #30210.

+    tree-object-size: Deterministic SSA generation [PR123351]
+    
+    The order of evaluation of function arguments is unspecified in C++.
+    The function object_sizes_set_temp called object_sizes_set with two
+    calls to make_ssa_name() as arguments.  Since make_ssa_name() has the
+    side effect of incrementing the global SSA version counter, different
+    architectures of the same compiler evaluated these calls in different
+    orders.
+    
+    This resulted in non-deterministic SSA version numbering between
+    x86_64 and aarch64 hosts during cross-compilation, leading to
+    divergent object files.
+    
+    Sequencing the calls into separate statements ensures deterministic
+    evaluation order.
