1. Calls to external global VARIABLES should not be treated as a call to an
external function
2. Efficiently deleting an element from a vector by using std::swap with
the back, then pop_back is NOT a good way to keep the vector sorted.
3. Our hope of having stuff get deleted by making them redundant just won't
work. In particular, if we have three calls in sequence that should be
merged: A, B, C first we unify B into A. To be sure that they appeared
identical (so B would be erased) we set B = A. On the next step, we
unified C into A and set C = A. Unfortunately, this is no guarantee that
C = B, so we would fail to delete the dead call. Switch to a more
explicit scheme.

* change some uses of NH.getNode() in a bool context to use !NH.isNull()
* Fix a bunch of places where we depended on the (undefined) order of
evaluation of arguments to function calls to ensure that getNode() was
called before getOffset(). In practice, this was NOT happening.

sub-makes and recursively append causing huge command lines and incorrect
compilation results.
Also, fix the printvars target to align its output and ensure that the
contents of variables can't get interpreted by the shell.

supported by specific versions of GCC.
It is left in place in case anyone wants to updated it for GCC 3.4 or
re-use it for earlier versions of GCC where it works.

* Move rules that build directories earlier in the file so that they are
always built before the things that depend on them. This enables a
parallel "dist-check" target.
* Fix use of TOOLLINKOPTS and TOOLLINKOPTSB (thanks to Henrik Bach)
* Standardize the output - some scripts using plain echo instead of $(ECHO)

Correct the dependency of the Lexer.o file on the constructed
llvmAsmParser.h header file. It is not the Lexer.cpp file that depends on
the header, its the output of compiling Lexer.cpp, Lexer.o
llvm-svn: 17289
* Ensure that BUILT_SOURCES depends on OBJ_DIR/Makefile so that they do not
get built before the Makefile is updated.
* Fix build script for yacc & lex files by stopping it from thwarting the
dependencies on the file. If the .y file changes, it needs to be rebuilt.
This also cleans up the problem with llvmAsmParser ALWAYS rebuilding its
Yacc files just to throw them away because there's no change.
