Convert PhyRegAlloc into a proper pass.

PhyRegAlloc.cpp:
 Don't include TargetMachine.h or TargetRegInfo.h, because these are provided
  by PhyRegAlloc.h.
 Merge class RegisterAllocator into class PhyRegAlloc.
 Simplify & move ctor, dtor to PhyRegAlloc.h.
 Make some of PhyRegAlloc's reference members into pointer members,
  so they can be more easily messed with.
 MarkAllocatedRegs() becomes a member method, with fewer args.

PhyRegAlloc.h:
 Include Pass.h, TargetMachine.h and TargetRegInfo.h. Don't declare
  TargetRegInfo forward.
 Give AddedInstrns the obvious clear() method.
 Make some of PhyRegAlloc's reference members into pointer members,
  so they can be more easily messed with.
 Add prototype for markAllocatedRegs().
 Remove unused inline void constructLiveRanges().

Do not put DEBUG() guard around error condition; this must *always* be printed.

Fix the flag on `rm' to properly do a recursive deletion.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8582 91177308-0d34-0410-b5e6-96231b3b80d8

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

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8580 91177308-0d34-0410-b5e6-96231b3b80d8

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.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8578 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...

fix misspelling analyse -> analyze

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8576 91177308-0d34-0410-b5e6-96231b3b80d8

Renamed the link page to llvmlink.html
Added initial pages for the extract and llvm-link commands.
Reworded the description of the -load option for analyze to hopefully make it
more clear.

new old testcase

Use new method

Change the semancics of the dropallrefs method

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8572 91177308-0d34-0410-b5e6-96231b3b80d8

Add new deleteBody method

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8571 91177308-0d34-0410-b5e6-96231b3b80d8

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).

Updated the name of the linker to llvm-link.
This should fix the MultiSource tests.

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.

Add missing apostrophe. It's been bugging me for years.

No really, years.

Regenerated configure with Misha's changes.
Now link is llvm-link and things are alphabetized.
