[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.

[sanitizer] Improve scanf interceptor
...
This a rewrite of the scanf parser. The new implementation is pretty close to
the spec, with a few shortcuts taken here and there. It is conservative, i.e.
it gives up parsing if it does not understand some part of the format string,
or runs into an ambiguous % spec. It does not handle some rarely used parts of
the spec, like %n$ - for now.
I'm also moving parser call to after the original *scanf function completes,
so that we can find out the store size of %s directive by the use of strlen()
on the target buffer.
