    According to asan_mapping.h mem range lower ~2G is safe for usage on all platforms.
    So memory map is set up for data in 0..1G and ELF in 1..2G.

    Typical shadow mapping on Linux/x86_64 with SHADOW_OFFSET == 0x00007fff8000:
    || `[0x10007fff8000, 0x7fffffffffff]` || HighMem    ||
    || `[0x02008fff7000, 0x10007fff7fff]` || HighShadow ||
    || `[0x00008fff7000, 0x02008fff6fff]` || ShadowGap  ||
    || `[0x00007fff8000, 0x00008fff6fff]` || LowShadow  ||
    || `[0x000000000000, 0x00007fff7fff]` || LowMem     ||

    When SHADOW_OFFSET is zero (-pie):
    || `[0x100000000000, 0x7fffffffffff]` || HighMem    ||
    || `[0x020000000000, 0x0fffffffffff]` || HighShadow ||
    || `[0x000000040000, 0x01ffffffffff]` || ShadowGap  ||

    Special case when something is already mapped between
    0x003000000000 and 0x005000000000 (e.g. when prelink is installed):
    || `[0x10007fff8000, 0x7fffffffffff]` || HighMem    ||
    || `[0x02008fff7000, 0x10007fff7fff]` || HighShadow ||
    || `[0x005000000000, 0x02008fff6fff]` || ShadowGap3 ||
    || `[0x003000000000, 0x004fffffffff]` || MidMem     ||
    || `[0x000a7fff8000, 0x002fffffffff]` || ShadowGap2 ||
    || `[0x00067fff8000, 0x000a7fff7fff]` || MidShadow  ||
    || `[0x00008fff7000, 0x00067fff7fff]` || ShadowGap  ||
    || `[0x00007fff8000, 0x00008fff6fff]` || LowShadow  ||
