0799e52fde util/llvmdisassembler: map registers by names
Internal LLVM register IDs can and did change between LLVM versions.
These magic integers are replaced by iterating over all LLVM registers
and mapping them to FAIL* registers by name.
As this iteration requires a LLVM object created from a binary, a static
convenience function is added to LLVMtoFailTranslator which creates a
translator given the binary filename. Building this functionality inside
libfail-llvmdisassembler prevents experiments from needing to add LLVM
includes and library definitions.

203ec6c5cc remove #ifndef __puma from code using LLVM
Contemporary AspectC++ versions can deal with the LLVM headers very
well, and #ifdef __puma stuff in Fail* headers results in
unmaintainable #ifdef __puma blocks in other parts of Fail* (e.g., the
trace importer).

Make sure you're using a 64-bit ac++ when living in a 64-bit userland
(the 32-bit version doesn't know about __int128), and be aware that
AspectC++ r325 introduced a regression that has not been fixed yet.

40f610b536 util: integrate LLVM-based Disassembler
The LLVM Disassembler infrastructure can be used to analyze many kinds
of ELF Binaries. For every instruction the used and defined registers
is available as well as information about the instruction itself.
