Peter Collingbourne 791e65dcfb Overhaul the symbolizer interface.
This moves away from creating the symbolizer object and initializing the
external symbolizer as separate steps.  Those steps now always take place
together.

Sanitizers with a legacy requirement to specify their own symbolizer path
should use InitSymbolizer to initialize the symbolizer with the desired
path, and GetSymbolizer to access the symbolizer.  Sanitizers with no
such requirement (e.g. UBSan) can use GetOrInitSymbolizer with no need for
initialization.

The symbolizer interface has been made thread-safe (as far as I can
tell) by protecting its member functions with mutexes.

Finally, the symbolizer interface no longer relies on weak externals, the
introduction of which was probably a mistake on my part.

Evgeniy Stepanov a59daaef3e [msandr] Add NATIVE_EXEC macro for building client for running in DynamoRIO hybrid mode only.
When running application in DynamoRIO hybrid mode only, only uninstrumented
modules will run in DynamoRIO and be instrumented by the client, so we do not
need module table in MSanDR.

Patch by Qin Zhao.

Stephen Hines 7633afc960 Switch __ARM_ARCH_7S__ to __ARM_ARCH_EXT_IDIV__ for use of sdiv/udiv assembly.
__ARM_ARCH_EXT_IDIV__ is the define that ARM is using to indicate the presence
of hardware integer divide (sdiv/udiv). Previously, this code was only being
invoked for processors marked 7S. We now can correctly generate hardware
divides on cortex-a15 devices.

Evgeniy Stepanov d280ee48e8 [msan] Fix invalid origin copying.
Origin copying may destroy valid origin info. This is caused by
__msan_copy_origin widening the address range to the nearest 4-byte aligned
addresses both on the left and on the right. If the target buffer is
uninitialized and the source is fully initialized, this will result in
overriding valid origin of target buffer with stale (possibly 0) origin of the
source buffer.

With this change the widened origin is copied only if corresponding shadow
values are non zero.
