I noticed that for member class templates of a class template we were
unnecessarily substituting both the template and its type. Avoiding that

Hi Jonathan,
Thank you for your review and suggestion. The change looks great!
Assigning a value with an immediate zero is indeed much faster.
in v2:
* revised the commit message a little bit, I found it a little bit
difficult to parse when re-reading it.
* associated the commit with PR/libstd
This patch always sets _M_string_length in the constructor specialized
for range of input_iterator, for the cases like istringstream.
We copy from source range to the local buffer, and then reallocate to
a larger one if necessary. When disposing the old buffer, the old buffer
could be provisioned
While improving replace_phi_edge_with_variable for the diamond formed bb

We try to cache the result of reduce_template_parm_level so that when we
