Dmitry Vyukov b332134921 tsan: new runtime (v3)
This change switches tsan to the new runtime which features:
 - 2x smaller shadow memory (2x of app memory)
 - faster fully vectorized race detection
 - small fixed-size vector clocks (512b)
 - fast vectorized vector clock operations
 - unlimited number of alive threads/goroutimes

Depends on D112602.

Dmitry Vyukov 8233c343ad tsan: add notion of compressed addresses
New tsan runtime will need to compress addresses/PCs to fewer bits.
Add CompressAddr/RestoreAddr functions that compress/restore
addresses to 44 bits.

Dmitry Vyukov 0ebfe7c312 tsan: unit-test all mappings
Move the mapping checking logic from startup to unit tests
and test all mapping instead of just the active one.
This makes it much more feasible to make any global changes
to the mappings since we have 17 of them.

Depends on D107740.

Dmitry Vyukov a82c7476a7 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.
