ARM: Refactor instaliases using TableGen support for #NAME#.

Now that TableGen supports references to NAME w/o it being explicitly
referenced in the definition's own name, use that to simplify
assembly InstAlias definitions in multiclasses.

Add support for the ARM GHC calling convention, this patch was in 3.0,
but somehow managed to be dropped later.

Patch by Karel Gardas.

Move the "findUsedStructTypes" functionality outside of the Module class.

The "findUsedStructTypes" method is very expensive to run. It needs to be
optimized so that LTO can run faster. Splitting this method out of the Module
class will help this occur. For instance, it can keep a list of seen objects so
that it doesn't process them over and over again.

Add new getLibFunc method to TargetLibraryInfo.

This just provides a way to look up a LibFunc::Func enum value for a
function name.  Alphabetize the enums and function names so we can use a
binary search.

Fall back to selection DAG isel for calls to builtin functions.

Fast isel doesn't currently have support for translating builtin function
calls to target instructions.  For embedded environments where the library
functions are not available, this is a matter of correctness and not
just optimization.  Most of this patch is just arranging to make the
TargetLibraryInfo available in fast isel.  <rdar://problem/12008746>

Add a BUILD_FLAGS variable so that autoconf checks have a place
to store additional flag options since too many things can
and do override CPPFLAGS. Also, this is exported, unlike CPPFLAGS
so it can be actually used elsewhere. This should enable us
to remove the AC_SUBSTs in the intel checks, but I have no way
of testing it.

allow 'make CPPFLAGS=<something>' work again

this makes this hack a bit more bearable
for poor souls who need to pass custom
preprocessor flags to the build process

Don't delete dead code in TwoAddressInstructionPass.
