As alternative to get ahold of the ELF file path in case name() doesn't return a full path.
…med sections E.g., this allows to conveniently scan for multiple named sections in a single pass.
... instead of relying on magic compiler symbols `_tls{start,end}` and
the apparently problematic magic linker symbol `_end`.
Also eagerly allocate the TLS per-thread-block to speed-up TLS lookup.
…canning As it apparently doesn't always end up at the start of the data segment, e.g., with the gold linker, see ldc-developers/ldc#3350 (comment). It should be rather small in most cases, especially in comparison to the ranges on the heap, so just don't bother.
