[Sanitizer] Allocator for internal runtime purposes. Currently it calls libcmalloc, but we might have to make it more low-level in future

[Sanitizer] Use common CHECK machinery. Currently each tool has to define its own CheckFailed function.

[asan] start compacting the allocator header, the goal is to make it 16 bytes w/o losing any information

[Sanitizer]: Introduce a common internal printf function. For now, also use tool-specific wrappers TsanPrintf (its output is controlled by TSan flags) and AsanPrintf (which copies its results to the ASan-private buffer). Supported formats: %[z]{d,u,x}, %s, %p. Re-write all format strings in TSan according to this format (this should have no effect on 64-bit platforms).

[Sanitizer] add sanitizer_common.h for routines shared between TSan and ASan runtimes. Use __sanitizer::Die() in TSan.

[ASan] fix GetFreeBytesTest interface test on 32-bit Linux - delete some assumptions about the behavior of allocator in test code

[Sanitizer] Use common defines for ASan and TSan runtime. Split defines between interface defines (can be visible in user code that includes interface ASan/TSan headers) and internal defines.

[asan] change the order of tests in the asan_test binary. Makes the test runs 2x faster due to DEATH_TEST overhead (see asan issue 77)
