This reduces the time actually spent doing string to ID conversion and shows a 10% improvement in compile time for a particularly bad case that involves ARM Neon intrinsics (these have many overloads).

This was causing the folding set to fail to fold attributes, because it was
being calculated in one spot without an empty values string but here with an
empty values string.

PR15262 reported a bug where the following instruction:

  i8 getelementptr inbounds i8* bitcast ([4 x i8] addrspace(12)* @buf to i8*),
                                i32 2

was getting folded into:

  addrspace(12)* getelementptr inbounds ([4 x i8] addrspace(12)* @buf, i32 0,
                                        i32 2)

This caused instcombine to crash because the original instruction and
the folded instruction have different types.  The issue was fixed by
disallowing bitcasts between different address spaces to be folded away.

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

Use a DenseMap instead of a std::map for AnalysisID -> Pass* maps. This reduces the pass-manager overhead from FPPassManager::runOnFunction() by about 10%.

the debug info for -gsplit-dwarf so we can encode that location

Listing all of the attributes for the callee of a call/invoke instruction is way
too much and makes the IR unreadable. Use references to attributes instead.

llvm-svn: 175877

llvm-svn: 175846

llvm-svn: 175843

The 'nobuiltin' attribute is applied to call sites to indicate that LLVM should
not treat the callee function as a built-in function. I.e., it shouldn't try to
replace that function with different code.

The slot that we're adding/removing the attribute from may not be the same as
the attribute coming in. Make sure that they match up before we try to
add/remove them.

This makes the LLVM assembly look better. E.g.:

     define void @foo() #0 { ret void }
     attributes #0 = { nounwind noinline ssp }

llvm-svn: 175605

Add the function attributes from an inline asm call. These don't have declarations that set the attribute groups, so we must do it on our own.

Fix a bug in mayHaveSideEffects. Functions that do not return are now considered as instructions with side effects.

Currently we're at 34. Bitset should compile into virtually the same code as
uint64_t here.

Paired with an Clang commit so this may cause temporary build failures.

llvm-svn: 175426

Previously we seemed to be assuming that all functions were definitions and all
methods were declarations. This may be consistent with how Clang uses DIBuilder
but doesn't have to be true of all clients (such as DragonEgg).

Avoids malloc and is a lot denser. We lose iteration over target independent
attributes, but that's a strange interface anyways and didn't have any users
outside of AttrBuilder.

Add static cast to unsigned char whenever a character classification function is called with a signed char argument, in order to avoid assertions in Windows Debug configuration.

This emits the attribute groups that are used by the functions. (It currently
doesn't print out return type or parameter attributes within attribute groups.)

Note: The functions still retrieve their attributes from the "old" bitcode
format (using the deprecated 'Raw()' method). This means that string attributes
within an attribute group will not show up during a disassembly. This will be
addressed in a future commit.
