that fit evenly within a natural integer type and those that don't.

1. Fix logic for executeGEP. Only 32-bit and 64-bit integer types are
   acceptable as indices.
2. Ensure that all integer cast operations truncate their result to the
   integer size of the operand.

Add the llvm.stacksave and llvm.stackrestore intrinsics that correspond
to the GCC builtins __builtin_stack_save and __builtin_stack_restore. This
allows the CBE to execute these builtins, and fixes:

   test/CodeGen/CBackend/2007-01-17-StackSaveNRestore.ll
   External/SPEC/CINT2000/176.gcc (CBE)

Patch by Gordon Henriksen.

Ensure the CBE generates calls to GCC builtins for stack_save and
stack_restore when it encounters the corresponding intrinsics.

Support overriding the prefix and DESTDIR variables from the make command
line. This makes the makefile system a little more GNU compliant and the
feature makes it easier for distribution builders to re-target the install
location of LLVM.

This can reduce size of binaries. Enable it by default for ELF &
Cygwin/Mingw targets. Probably, Darwin should be also added.
