Rationalize warning suppression.  First, 64-bit portability warnings are disabled.  The
specific warnings they produced were being suppressed anyway.  The truncation warnings

The only warnings suppressed now are the "negating an unsigned is still unsigned", the
validity of which Chris does not accept, and the "implicit conversion of <type> to bool
performance warning".  Making the conversion explicit won't make it run any faster and
this is an easier way to shut the compiler up.

Add spaces between rule groups to make it more obvious which ones pair

Remove instrselector generation, remove Intel/ATT specifics from Makefile.rules.

Adjust to changes in asmwriter filenames

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18987 91177308-0d34-0410-b5e6-96231b3b80d8

When tblgen changes, regenerate all .inc files, but do not rebuild any .o
files that USE the .inc file unless the contents of the .inc file changes.

This should fix the problem where reconfiguring causes all targets to be
completely rebuilt (because config.h is usually modified, causing libsystem
to be rebuilt, causing tblgen to be rebuilt, causing .inc files to be
rebuilt, causing .o files to be rebuilt).

This patch also checks in a gross hack where .o files now explicitly depend
on $(BUILT_SOURCES), to avoid problems where the .inc files are not completely
generated before the .o files start to compile.

Add a "make spotless" rule for environments with BUILD_OBJ_ROOT not equal
to BUILD_OBJ_SRC. This will save the config.status and mklib files, then
wipe out the BUILD_OBJ_ROOT, copy back config.status and mklib, and then
run config.status to regenerate the makefiles. This target gives you a
completely clean/fresh BUILD_OBJ_ROOT.

Get rid of extraneous dependencies on $(BUILT_SOURCES) now that we've fixed

Fix a major bug with BUILT_SOURCES. You actually have to dereference a
variable before you can filter its value. Duh!
