commit ebfe8b28d40746ff33724bd5b9ade2552e619213

c++: 'this' adjustment for devirtualized call
My patch for 95719 made us do a better job of finding the actual virtual
function we want to call, but didn't update the 'this' pointer adjustment to
match.
This backport also incorporates a bit of the r11-1638 reorganization.

Subject: [PATCH] c++: mangling of lambdas in default args [PR91241]
In this testcase, the parms remembered in LAMBDA_EXPR_EXTRA_SCOPE are no
longer the parms of the FUNCTION_DECL they have as their DECL_CONTEXT, so we
were mangling both lambdas as parm #0. But since the parms are numbered
from right to left we don't need to need to find them in the FUNCTION_DECL,
we can measure their own DECL_CHAIN.
gcc/cp/ChangeLog:
PR c++/91241
* mangle.c (write_compact_number): Add sanity check.
(write_local_name): Use list_length for parm number.
