ddd3a8899a Fix a minor bug which resulted in intermediate calculations 
using wider types than are necessary.

9f6a6862be Change this llvm_unreachable to report_fatal_error, since it can 
be triggered by valid, if dubious, IR.

459a36bd34 While spilling live registers at the end of block check whether they are used by DBG_VALUE machine instructions or not. If a spilled register is used by DBG_VALUE machine instruction then insert a new DBG_VALUE machine instruction to encode variable's new location on stack.

b57e6558c7 Experiments show that we can safely increase our unrolling threshold without unduly impacting code size, particularly 
since unrolling is not enabled at -Os.

c575283675 Print an error message when someone tries -integrated-as on an unsupported target. 
- The COFF backend doesn't support MingW/Cygwin at the moment, it'll report an
  error, but it's still much better than random assertions from the MachO backend.
- We want to make ELF the default eventually, it's what the majority of targets use.

ac27ec0f5b by Alexander Herz: 
"The CWriter::GetValueName() method does not check if a value as an alias 
and emits the alias name which will never be defined in the output .c 
file (so the output file fails to compile). This can happen if you have 
multiple inheritance with several destructors defined by clang (...D0Ev, 
...D1Ev, ...D2Ev)."

-- applied with minor tweaks. Thanks!

79fca6fea8 Thread const correctness through a bunch of AliasAnalysis interfaces and 
eliminate several const_casts.

Make CallSite implicitly convertible to ImmutableCallSite.

Rename the getModRefBehavior for intrinsic IDs to
getIntrinsicModRefBehavior to avoid overload ambiguity with CallSite,
which happens to be implicitly convertible to bool.

normalization.

This change could affect register allocation. Hopefully for the better.

ab37f50838 Make SCEVUnknown a CallbackVH, so that it can be notified directly 
of Value deletions and RAUWs, instead of relying on ScalarEvolution's
Scalars map being notified, as that's complicated at best, and
insufficient in general.

This means SCEVUnknown needs a non-trivial destructor, so introduce
a mechanism to allow ScalarEvolution to locate all the SCEVUnknowns.
