Peter Eisentraut fa16e7fd84 Revert "Replace pg_restrict by standard restrict" 
This reverts commit f0f2c0c1ae.

The original problem that led to the use of pg_restrict was that MSVC
couldn't handle plain restrict, and defining it to something else
would conflict with its __declspec(restrict) that is used in system
header files.  In C11 mode, this is no longer a problem, as MSVC
handles plain restrict.  This led to the commit to replace pg_restrict
with restrict.  But this did not take C++ into account.  Standard C++
does not have restrict, so we defined it as something else (for
example, MSVC supports __restrict).  But this then again conflicts
with __declspec(restrict) in system header files.  So we have to
revert this attempt.  The comments are updated to clarify that the
reason for this is now C++ only.
