Split each select function for a particular opcode into multiple ones. One
per possible ValueType of the node. e.g. Select_add is split into Select_add_i8,
Select_add_i16, etc.

For opcodes which do not produce a non-chain result, it is split on the
ValueType of its first non-chain operand. e.g. Select_store.

On X86 / Mac OS X, Select_store used to be the largest function. It had a stack

For PR848:
1. Get the path to the pwd binary (/bin/pwd usually) from configure.
2. Use that path to run pwd in all path variables set in Makefile.config.in
The hope is that these changes will resolve symlinks to physical paths. This
should work on all platforms where the binary pwd defaults to printing
physical paths. The shell version of pwd generally doesn't (it will print
the symlink path).

This commit improves bugpoints speed. On my G4 this changed caused kimwitu++ to run through bugpoint in 1091.15 seconds (user + system time). The time it took to run this on my G4 before I made these changes is 1420.82 seconds (user + system time). This is a speedup of about 5.5 minutes.

This is faster because SplitFunctionsOutOfModule no longer calls Clone Module and then removes the functions it doesnt want from the module returned. Instead it creates a module and copies over the specified functions, making changes to the new and old module where neccessary. This reduces the memory demand.

Changes to support cross-compiling LLVM. The GenLibDeps.pl script needs to
have a compile-host version of "nm", not build-host. In order to effect this

through the makefiles, through llvm-config and finally to GenLibDeps.pl as
an optional argument.

Use std::copy instead of custom loops to take advantage of STL optimizations.
Add a new append method for appending a range.

I made a stupid mistake when adding support for -use-gmake. ~PJ

added support for the -use-gmake option. This will come in handy when running the test on SunOS.

This change will allow support for SunOS to the testing script. It adds a check to see if we're running on SunOS and if so, then uses gmake instead of make.
