WIP: pragma block reduction

[rwgk]

Spreadsheet: pybind11.h v2.7.0 pragma block analysis

Approach:

for pragma in pragmas:
    remove_from_pybind11_h(pragma)
    run_ci_with_tests_disabled()
    collect_logs()
manually_sort_through_logs()
manually_add_local_pragma_push_pop()

Keeping track of some simple results here:

• GCC -Wunused-but-set-parameter needs work
• GCC -Wunused-but-set-variable rm_ok
• GCC -Wmissing-field-initializers rm_ok
• GCC -Wattributes needs work
• GCC -Wnoexcept-type needs work (gcc 7 only)
• MSVC C4100 needs work
• MSVC C4127 needs work
• MSVC C4512 rm_ok
• MSVC C4800 needs work
• MSVC C4996 needs work
• MSVC C4702 rm_ok
• MSVC C4522 needs work
• MSVC C4505 needs work
• ICC 186 rm_ok
• ICC 878 needs work
• ICC 1334 rm_ok
• ICC 1682 rm_ok
• ICC 1786 rm_ok
• ICC 1875 rm_ok
• ICC 2196 needs work
