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
