Kostya Serebryany [Fri, 20 Jan 2012 17:56:17 +0000 (17:56 +0000)]
Extend Attributes to 64 bits

Problem: LLVM needs more function attributes than currently available (32 bits).
One such proposed attribute is "address_safety", which shows that a function is being checked for address safety (by AddressSanitizer, SAFECode, etc).

Solution:
- extend the Attributes from 32 bits to 64-bits
- wrap the object into a class so that unsigned is never erroneously used instead
- change "unsigned" to "Attributes" throughout the code, including one place in clang.
- the class has no "operator uint64 ()", but it has "uint64_t Raw() " to support packing/unpacking.
- the class has "safe operator bool()" to support the common idiom:  if (Attributes attr = getAttrs()) useAttrs(attr);
- The CTOR from uint64_t is marked explicit, so I had to add a few explicit CTOR calls
- Add the new attribute "address_safety". Doing it in the same commit to check that attributes beyond first 32 bits actually work.
- Some of the functions from the Attribute namespace are worth moving inside the class, but I'd prefer to have it as a separate commit.

Tested:
"make check" on Linux (32-bit and 64-bit) and Mac (10.6)
built/run spec CPU 2006 on Linux with clang -O2.

This change will break clang build in lib/CodeGen/CGCall.cpp.

- Slight change to finalizeBundle() interface. LastMI is not exclusive (pointing
  to instruction right after the last instruction in the bundle.
- Add a finalizeBundle() variant that doesn't specify LastMI. Instead, the code
  will find the last instruction in the bundle by following the 'InsideBundle'
  marker. This is useful in case bundles are formed early (i.e. during MI
  scheduling) but finalized later (i.e. after register allocator has finished
  rewriting virtual registers with physical registers).
