[ASan] Speed-up initialization-order checking: create and use fast versions of PoisonShadow functions, store copies of __asan_global descriptors in a vector instead of list of pointers. This gives 3x speedup on both benchmarks and real binaries with lots of globals.

[asan] make asan work with 7fff8000 offset and prelink
...
When prelink is installed in the system, prelink-ed
libraries map between 0x003000000000 and 0x004000000000 thus occupying the shadow Gap,
so we need so split the address space even further, like this:
|| [0x10007fff8000, 0x7fffffffffff] || HighMem ||
|| [0x02008fff7000, 0x10007fff7fff] || HighShadow ||
|| [0x004000000000, 0x02008fff6fff] || ShadowGap3 ||
|| [0x003000000000, 0x003fffffffff] || MidMem ||
|| [0x00087fff8000, 0x002fffffffff] || ShadowGap2 ||
|| [0x00067fff8000, 0x00087fff7fff] || MidShadow ||
|| [0x00008fff7000, 0x00067fff7fff] || ShadowGap ||
|| [0x00007fff8000, 0x00008fff6fff] || LowShadow ||
|| [0x000000000000, 0x00007fff7fff] || LowMem ||
Do it only if necessary.
Also added a bit of profiling code to make sure that the
mapping code is efficient.
Added a lit test to simulate prelink-ed libraries.
Unfortunately, this test does not work with binutils-gold linker.
If gold is the default linker the test silently passes.
Also replaced
__has_feature(address_sanitizer)
with
__has_feature(address_sanitizer) || defined(__SANITIZE_ADDRESS__)
in two places.
Patch partially by Jakub Jelinek.

[Sanitizer/ASan] Simplify the code that prints and symbolizes stack traces. Fall back to module+offset if user-provided symbolizer failed. Use weak function __asan_symbolize instead of __asan_set_symbolize_callback in ASan interface, so that we're able to symbolize reports for errors that happen before the main() is called, for example, during module initialization.
