tsan: reset destination range in Java heap move
Switch Java heap move to the new scheme required for the new tsan runtime.
Instead of copying the shadow we reset the destination range.
The new v3 trace contains addresses of accesses, so we cannot simply copy the shadow.
This can lead to false negatives, but cannot lead to false positives.

tsan: introduce RawShadow type
Currently we hardcode u64 type for shadow everywhere
and do lots of uptr<->u64* casts. It makes it hard to
change u64 to another type (e.g. u32) and makes it easy
to introduce bugs.
Introduce RawShadow type and use it in MemToShadow, ShadowToMem,
IsShadowMem and throughout the code base as u64 replacement.
This makes it possible to change u64 to something else in future
and generally improves static typing.

tsan: s/CHECK/DCHECK/ in tsan_interface_java.cpp
We are very paranoid with CHECKs in all Java entry points.
These CHECKs were added along with Java support.
At that point it wasn't clear what exactly to expect from JVM part
and if JVM part is correct or not. Thus CHECK paranoia.
These CHECKs never fired in practice, but we pay runtime cost
in every entry point all the time.
Replace CHECKs with DCHECKs.

tsan: don't use caller/current PC in Java interfaces
Caller PC is plain harmful as native caller PC has nothing to do with Java code.
Current PC is not particularly useful and may be somewhat confusing for Java users
as it makes top frame to point to some magical __tsan function.
But obtaining and using these PCs adds runtime cost for every java event.
Remove these PCs. Rely only on official Java frames.
It makes execution faster, code simpler and reports better.

Don't confuse readers and don't pretend that pc is needed
