c++: conversion location
It seems more useful for a conversion to have the location of the source
expression rather than the enclosing expression, such as a call that might
convert multiple arguments in different ways.
As a result, in srcloc17.C the recorded location of 'e' when
copy-initialized became that of the initializer rather than the variable,
since the semantic was to convert the initializer (at its location) and then
initialize the variable from the resulting prvalue. If we instead
direct-initialize the variable, the location of the constructor call is that
of the variable.
gcc/cp/ChangeLog:
* call.cc (convert_like_internal) [ck_user]: Use iloc_sentinel.
gcc/testsuite/ChangeLog:
* g++.dg/cpp2a/srcloc17.C: Adjust initialization.
