vector_algorithms.cpp: turn tails #3963
Description
There are some scalar tails extracted in vector_algorithms.cpp,
Whereas some are used multiple times, some are used just one. A few examples:
STL/stl/src/vector_algorithms.cpp
Lines 1057 to 1058 in 8674b3d
STL/stl/src/vector_algorithms.cpp
Line 1396 in 8674b3d
STL/stl/src/vector_algorithms.cpp
Line 1345 in 8674b3d
The tail extraction does not serve any purpose in such cases, it only provides an obstacle for debugging of optimized code (as tails are expectedly inlined. so the debugger does not navigate the lines).
