8d7bab5e63 Add our own version of libtool.m4 instead of relying on the installed one. 
This is a potential version mismatch problem because this file came from
libtool 1.5.10. If you're running a different version of libtool, the
checks in this file may not be quite right. Having our own version of this
file violates the spirit of libtool and is only provided to change the name
of "libtool" to "mklib". This is done so that the name "libtool" does not
conflict with the "lib" directory when doing tab completion and your
$objdir == $srcdir.

e6755fe307 Fix a nasty iterator invalidation problem I introduced yesterday. This 
unfortunately is the cause of a bunch of failures from tonight, and the
reason the tester is running so slow :(

98d434988e Remove a whole bunch of horrible hacky code that was used to promote allocas 
whose addresses where used by trivial phi nodes and select instructions.  This
is now performed by the instcombine pass, which is more powerful, is much
simpler, and is faster.  This allows the deletion of a bunch of code, two
FIXME's and two gotos.

12bcdf2e01 Fix the inliner to always delete any edges from the external call node to 
a function being deleted.  Due to optimizations done while inlining, there
can be edges from the external call node to a function node that were not
apparent any longer.

This fixes the compiler crash while compiling 175.vpr
