The current heuristic assumes that there can't be binary operators in
builder-type calls (excluding assigments). However, it also excluded
< and > in general, which is wrong. Now they are only excluded if they
are template parameters.

Currently, changes made by previous transforms are not kept if a transform
doesn't make any changes itself to a given file. Now file states are propagated
properly through transforms that don't make changes.

This got lost and was untested as the same effect is achieved by
avoiding bin packing, which is active in Google style by default.
However, moving forward, we want more control over the bin packing
option(s) and thus, this flag should work as expected.

MaybeReexec() does now a tricky job to manage DYLD_INSERT_LIBRARIES in a safe way.

Because we're using library interposition, it's critical for an instrumented app
to be executed with the runtime library present in DYLD_INSERT_LIBRARIES list.
Therefore if it's initially missing in that list, we append the runtime library name
to the value of DYLD_INSERT_LIBRARIES and then exec() ourselves.

On the other hand, some of the apps exec()ed by our program may not want to have
ASan runtime library preloaded, so we remove the runtime library from the
DYLD_INSERT_LIBRARIES if it's already there.

Users may want to preload other libraries using DYLD_INSERT_LIBRARIES, so we preserve those.

This is essentially a stripped-down version of the ConstandIslands pass (which
always had these two functions), providing just the features necessary for
correctness.

In particular there needs to be a way to resolve the situation where a
conditional branch's destination block ends up out of range.

This issue crops up when self-hosting for AArch64.

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
