Doublings are a little bit faster than additions, so use them half

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

make start code more versatile
...
* always align the stack to 16. I saw an instance on x86_64 linux where
it was needed.
* detect at runtime if being interpreted by a dynamic loader and if so
avoid clobbering the fs register.

Update the minimum cmake version we require
...
Recent versions of cmake complain about it:
<<
CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
Compatibility with CMake < 2.8.12 will be removed from a future version of
CMake.
>>
We don't require anything from version 2.8.5, and version 2.8.12 was
released in 2011, so it is very unlikely that anyone still uses 2.8.5.

Fix the ELF base calculation
...
Find the effective ELF load address in dl_iterate_phdr by computing the
difference between the in-memory phdr and its p_vaddr specified in the
ELF file.
This makes the dl_iterate_phdr test pass and restores the stack traces.
