libstdc++: Optimize operator+(string/char*, char*/string) equally
Until now operator+(char*, const string&) and operator+(const string&,
char*) had different performance characteristics. The former required a
single memory allocation and the latter required two. This patch makes
the performance equal.
libstdc++-v3/ChangeLog:
* include/bits/basic_string.h (operator+(const string&, const char*)):
Remove naive implementation.
* include/bits/basic_string.tcc (operator+(const string&, const char*)):
Add single-allocation implementation.
