Fix indirect call inlining with AutoFDO 

The histogram value for indirect calls was incorrectly set up.
That is fixed now.

With this change the tree-prof tests checking indirect call inlining with AutoFDO
in gcc.dg and g++.dg are passing.

Resolves:
PR gcov-profile/71672 - inlining indirect calls does not work with autofdo
