[lto] cp/call.c: Use compparms in build_op_delete_call.

[Kazu Hirata]

Hi,

Attached is a patch to use compparms in build_op_delete_call.

The lines removed by this patch does exactly what compparms does.

This patch replaces those lines with compparms while reducing use of
TREE_CHAIN on parameter type lists.

Tested on x86_64-pc-linux-gnu.  OK to apply to the LTO branch (and 4.3
once in Stage 1)?
