#146562 made
[TestCallStdStringFunction](bd6cd92984/lldb/test/API/commands/expression/call-function/TestCallStdStringFunction.py)
unexpectedly pass on Windows.
The test now passes, because `expression str` now prints the "raw"
string object, which happens to include the string "Hello world".
Previously, this resulted in an error:
```
(lldb) expression str
(std::string) $0 = {
_Mypair = {
_Myval2 = {
_Bx = (_Buf = "Hello world", _Ptr = "", _Alias = "Hello world")
_Mysize = 11
_Myres = 15
}
}
}
(lldb) type summary add std::string --summary-string "${var._M_dataplus._M_p}"
^^^ previous summary ^^^
(lldb) expression str
(std::string) $1 = error: summary string parsing error
```
#143177 will eventually add the correct summary for MSVC STL strings.
