Removed linking functionality from gccld.cpp and moved it to linker.cpp.
Renamed functions that were all lower-case.
Moved functions from util.cpp into linker.cpp or gccld.cpp.
Removed util.h and created gccld.h.
Refactored the linker functionality in linker.cpp so that it is easier to
follow, easier to modify, and it's library/object file search behavior is
easier to understand and document.
Added code to include library paths when doing native linking, but this
causes problems and is currently #ifdef'd out.

In ExecWait(), made the child process exit if it can't execve() the new

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.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8579 91177308-0d34-0410-b5e6-96231b3b80d8

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).

Fix bug raising allocations whose call sites were invoke instructions.
Thanks to brg for tracking down the problem so precisely!

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8568 91177308-0d34-0410-b5e6-96231b3b80d8

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.

Allow multiple object trees to use the source tree tests at once by

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

Put llvm .bc files into the BytecodeObj subdirectory instead of the Bytecode

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

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

Added code that verifies that the source directory has not been configured

Update makellvm to work with the brave new world of separate obj-root trees.
With these changes, you can still run makellvm directly from your source tree
as follows:
  % makellvm [toolname] ## looks for obj-root in default places (see below)
or
  % makellvm -obj obj-root [toolname] ## specify obj-root explicitly.

With the first from, `makellvm' checks the following places in order
and uses the first one that contains the file `Makefile.config':
(1) Your src-root directory
(2) /localhome/$USER/llvm
Other choices can be added to this list.
