 Fix the alignment of TLS initialised data for __HAVE_TLS_VARIANT_I
 platforms by registering the largest alignment required and allocating
 memory accordingly. Additionally calculate correct offsets for each
 object's data relative to the end of the struct tls_tcb placed at the
 beginning of the TCB.
 
 This makes the tests/libexec/ld.elf_so:t_tls_alignment pass.
 
 I also tested it against a program that attempts to dlopen a DSO that
 (erroneously) attempts to use tls_model("initial-exec") and it correctly
 failed with
 
     Use of initialized Thread Local Storage with model initial-exec and dlopen is not supported
