f4a0f32d34 Fast-path improvement: reduce # of branches and unnecessary operations.
- Combine multiple runtime branches into a single malloc_slow check.
- Avoid calling arena_choose / size2index / index2size on fast path.
- A few micro optimizations.

e8ab0ab9c0 Add function to destroy tree
ex_destroy iterates over the tree using post-order traversal so nodes
can be removed and processed by the callback function without paying the
cost to rebalance the tree. The destruction process cannot be stopped
once started.

566d4c0240 use correct macro definitions for clang-cl
clang-cl, an MSVC-compatible frontend built on top of clang, defined
_MSC_VER *and* supports __attribute__ syntax.  The ordering of the
checks in jemalloc_macros.h.in, however, do the wrong thing for
clang-cl, as we want the Windows-specific macro definitions for
clang-cl.  To support this use case, we reorder the checks so that
_MSC_VER is checked first (which includes clang-cl), and then
JEMALLOC_HAVE_ATTR) is checked.  No functionality change intended.

fed1f9f367 Fix intermittent xallocx() test failures.
Modify xallocx() tests that expect to expand in place to use a separate
arena.  This avoids the potential for interposed internal allocations
from e.g. heap profile sampling to disrupt the tests.

This resolves #286.

a784e411f2 Fix a xallocx(..., MALLOCX_ZERO) bug.
Fix xallocx(..., MALLOCX_ZERO to zero the last full trailing page of
large allocations that have been randomly assigned an offset of 0 when
--enable-cache-oblivious configure option is enabled.  This addresses a
special case missed in d260f442ce (Fix
xallocx(..., MALLOCX_ZERO) bugs.).

044047fae1 Remove fragile xallocx() test case.
In addition to depending on map coalescing, the test depended on
munmap() being disabled so that chunk recycling would always succeed.

d36c7ebb00 Work around an NPTL-specific TSD issue.
Work around a potentially bad thread-specific data initialization
interaction with NPTL (glibc's pthreads implementation).

03eb37e8fd Make mallocx() OOM test more robust.

allocate the majority of virtual address space in a single contiguous
region.

d260f442ce Fix xallocx(..., MALLOCX_ZERO) bugs.
Zero all trailing bytes of large allocations when
--enable-cache-oblivious configure option is enabled.  This regression
was introduced by 8a03cf039c (Implement
cache index randomization for large allocations.).

Zero trailing bytes of huge allocations when resizing from/to a size
class that is not a multiple of the chunk size.

fb64ec29ec Fix prof_tctx_dump_iter() to filter.
Fix prof_tctx_dump_iter() to filter out nodes that were created after
heap profile dumping started.  Prior to this fix, spurious entries with
arbitrary object/byte counts could appear in heap profiles, which
resulted in jeprof inaccuracies or failures.

3263be6efb Simplify imallocx_prof_sample().
Simplify imallocx_prof_sample() to always operate on usize rather than
sometimes using size.  This avoids redundant usize computations and
more closely fits the style adopted by i[rx]allocx_prof_sample() to fix
sampling bugs.

38e2c8fa9c Fix ixallocx_prof_sample().
Fix ixallocx_prof_sample() to never modify nor create sampled small
allocations.  xallocx() is in general incapable of moving small
allocations, so this fix removes buggy code without loss of generality.

708ed79834 Resolve an unsupported special case in arena_prof_tctx_set().
Add arena_prof_tctx_reset() and use it instead of arena_prof_tctx_set()
when resetting the tctx pointer during reallocation, which happens
whenever an originally sampled reallocated object is not sampled during
reallocation.

This regression was introduced by
594c759f37 (Optimize
arena_prof_tctx_set().)

Fix prof_realloc() to call prof_free_sampled_object() after calling
prof_malloc_sample_object().  Prior to this fix, if tctx and old_tctx
were the same, the tctx could have been prematurely destroyed.

Make one call to prof_active_get_unlocked() per allocation event, and
use the result throughout the relevant functions that handle an
allocation event.  Also add a missing check in prof_realloc().  These
fixes protect allocation events against concurrent prof_active changes.
