58c2bec589 stage1: Fix ICE when generating struct fields with padding 
Make gen_const_ptr_struct_recursive aware of the possible presence of
some trailing padding by always bitcasting the pointer to its expected
type.

Not an elegant solution but makes LLVM happy and is consistent with how
the other callsites are handling this case.

Fixes #5398

abc717f203 modernize the PIE patch for the latest master branch 
This is the part of #3960 that has to be rewritten to apply to latest
master branch code.

55ab50efbd Merge branch 'piepiepie' of https://github.com/LemonBoy/zig into pie 
Conflicts:
 lib/std/dynamic_library.zig (fixed in this commit)
 src/all_types.hpp
 src/codegen.cpp
 src/link.cpp
 src/main.cpp

Will manually apply the diffs to these deleted files to the new zig
code in a followup commit.

stage2: Make zig cc more verbose (#7166) 
* stage2: Make zig cc more verbose

Make `zig cc` print more info from Clang itself and from our own linker
invocation, this is needed for CMake to properly discover all the
include directories and library search paths.

Closes #7110

* Update `update_clang_options`

* Typo fixes
