Schalk Krüger b44e84086f Refactor LG_VADDR detection in configure.ac
The LG_VADDR detection block accumulated duplicated logic and the rdtscp
feature probe was interleaved with virtual-address-bit detection.

Consolidate the detection:
- Wrap the whole case in a single "if LG_VADDR = detect" guard instead
  of repeating it in every "case" section.
- Define LG_VADDR exactly once, after the case.
- Check the cache variable directly for the x86_64 error path.
- Move the rdtscp probe into its own x86_64 case so it stays independent
  of LG_VADDR detection (it must run even when --with-lg-vaddr is given).

There is no functional change. Verified on x86_64 that LG_VADDR and
JEMALLOC_HAVE_RDTSCP are identical to before for auto-detection, and that
--with-lg-vaddr still probes rdtscp.

jemalloc is a general purpose malloc(3) implementation that emphasizes
fragmentation avoidance and scalable concurrency support.  jemalloc first came
into use as the FreeBSD libc allocator in 2005, and since then it has found its
way into numerous applications that rely on its predictable behavior.  In 2010
jemalloc development efforts broadened to include developer support features
such as heap profiling and extensive monitoring/tuning hooks.  Modern jemalloc
releases continue to be integrated back into FreeBSD, and therefore versatility
remains critical.  Ongoing development efforts trend toward making jemalloc
among the best allocators for a broad range of demanding applications, and
eliminating/mitigating weaknesses that have practical repercussions for real
world applications.

The COPYING file contains copyright and licensing information.

The INSTALL file contains information on how to configure, build, and install
jemalloc.

The ChangeLog file contains a brief summary of changes for each release.
