Andrey Semashev b2c6d37a1a Added byte/word-wide implementations of atomic ops on ARM.

Use ldrexb/w and strexb/w on ARMv7 and later to implement byte/word-wide
atomic ops. On the older ARM versions we still have to use 32-bit
widening implementation.

Also allowed immediate constants in some of the operations to improve
generated code.

Common ARM code extracted to a separate header to reuse with extra ops.
