  Log Message:
  -----------
  Comment no nested calls occur in cm3 IR.

Comment the fact that nested calls in source code are unnested in
cm3 intermediate representation.  This is an essential invariant
to both producers and consumers of this IR.

  Log Message:
  -----------
  Revert an incorrect fix due to misdiagnosis.

The actual problem here was not a lack of a set_source_file,
it was reading binary cm3 IR with the ascii reader.

  Log Message:
  -----------
  Big merge of changes to M3CG_LLVM.m3 from package llvm into package llvm3.6.1

Lots of changes happened to this file in package llvm, while the version
in package llvm3.6.1 has been undergoing integration with the greatly
altered llvm interfaces in llvm 3.6.1.  Merge these into the  M3CG_LLVM.m3
found in package llvm3.6.1.  Also some random manual review and fixes.

Compiles and runs to completion, with superficially believable output,
on one small test case involving separate temporaries in and out of
a FINALLY procedure.

Works with cm3 command, when its executable m3llvm has been shipped.

The test compile fails to link, not finding alloca.  m3llvm needs to
detect calls on alloca and translate internally into llvm alloca
instructions, rather than letting them through to be linked in.
