Change FunctionInfo from being an annotation put on Functions to be
something which is mapped from functions.

Removed the use of the environ variable and instead use the environment array
passed into main().  This may (or may not) be more portable, but it looks
nicer.
Added functions to copy the environment array and modify the copy, thus
preserving the environment.
Switched from using system() to using ExecWait().
The code now removes the assembly file generated when using the -native option.
Fixed the remove_env() function: The previous revision truncated the
environment variable list.  This version just zaps the variable as intended.

Added the ExecWait() function.  It executes a program with the specified
arguments and environment.
Perhaps it should be merged with the RunProgramWithTimeout function, but I'd
want to allow it to inherit the parent process's stdin and stdout.
I'll save that for a rainy day...

Added the -native option.
With this option, gccld links the program into LLVM bytecode and a native code
binary.  This allows llvmgcc to correctly tell GNU configure scripts when
things aren't defined properly (because the native link will fail).

This is effectively a complete rewrite of the globaldce algorithm, resulting
in it being both shorter and more effective.  It no longer depends on the
callgraph, so one FIXME has been fixed.

Additionally, this pass was not able to delete recursive (but dead) functions
if they were pointed to by global variables which were also dead.  In fact
this pass had a lot of problems deleting functions which were only pointed
to by dead globals and other stuff.

Fixing this means that the entire EH library should be stripped away now from
programs that don't use sjlj or exceptions.

Have the configure script put llvm.py into the object root.
The QMTest program can then use that as the location for loading test and

QMTest test and resource classes are always register before running the tests.
This ensures that any python bytecode generated by another platform is

Perferably, a better method will be implemented in the next few weeks.

Do not return success after checking only the FIRST USE of a gep instruction.

Fixed SPEC so that it would run correctly with the new autoconf-style object
directory.
Cleaned up the Makefile so that it uses VPATH to find source files.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8477 91177308-0d34-0410-b5e6-96231b3b80d8

directory.
Added Makefile.spec to the list of files to copy to the object directory.

Fixed SPEC so that it would run correctly with the new autoconf-style object
directory.
Added Makefile.spec to the list of files to copy to the object directory.
Moved the configuration of $SourceDir to Makefile.config and corrected the

VPATH.
