[asan] when creating string constants, set unnamed_attr and align 1 so that equal strings are merged by the linker. Observed up to 1% binary size reduction.

[asan] don't instrument functions with available_externally linkage. This saves a bit of compile time and reduces the number of redundant global strings generated by asan (https://code.google.com/p/address-sanitizer/issues/detail?id=167) 2013-03-18T07:33:49ZKostya Serebryanykcc@google.com2013-03-18T07:33:49Zurn:sha1:3797adb94fdc6b747cb0e97a64b15b931f2533b8

Split out filename & directory from DIFile to start generalizing over DIScopes2013-03-17T21:13:55ZDavid Blaikiedblaikie@gmail.com2013-03-17T21:13:55Zurn:sha1:b4cf0ab22b5a3ebb720f0b7287fdccfb465b6b7c
This is the first step to making all DIScopes have a common metadata prefix (so
that things (using directives, for example) that can appear in any scope can be
added to that common prefix). DIFile is itself a DIScope so the common prefix
of all DIScopes cannot be a DIFile - instead it's the raw filename/directory
name pair.

Unify clang/llvm attributes for asan/tsan/msan (LLVM part)2013-02-26T06:58:09ZKostya Serebryanykcc@google.com2013-02-26T06:58:09Zurn:sha1:8eec41fc778e99d42172a7f6de76faa43a6d8847
These are two related changes (one in llvm, one in clang).
LLVM:
- rename address_safety => sanitize_address (the enum value is the same, so we preserve binary compatibility with old bitcode)
- rename thread_safety => sanitize_thread
- rename no_uninitialized_checks -> sanitize_memory
CLANG:
- add __attribute__((no_sanitize_address)) as a synonym for __attribute__((no_address_safety_analysis))
- add __attribute__((no_sanitize_thread))
- add __attribute__((no_sanitize_memory))
for S in address thread memory
If -fsanitize=S is present and __attribute__((no_sanitize_S)) is not
set llvm attribute sanitize_S

[asan] instrument invoke insns with noreturn attribute (as well as call insns)2013-02-20T12:35:15ZKostya Serebryanykcc@google.com2013-02-20T12:35:15Zurn:sha1:1479c9bb392325688b72e5829bbb7939c4a079a4

[asan] instrument memory accesses with unusual sizes2013-02-19T11:29:21ZKostya Serebryanykcc@google.com2013-02-19T11:29:21Zurn:sha1:6ecccdbb2bf24a011b9c8ecbdd39be5a02269670
This patch makes asan instrument memory accesses with unusual sizes (e.g. 5 bytes or 10 bytes), e.g. long double or
packed structures.
Instrumentation is done with two 1-byte checks
(first and last bytes) and if the error is found
__asan_report_load_n(addr, real_size) or
__asan_report_store_n(addr, real_size)
is called.
Also, call these two new functions in memset/memcpy
instrumentation.
asan-rt part will follow.
