c8d5fc4461 Fix PR988 and CodeGen/Generic/2006-11-06-MemIntrinsicExpand.ll. 
The low part goes in the first operand of expandop, not the second one.

1f3ff6bcfe Tab interferes with uniqueness. 
NOTE: There doesn't seem to be consistency for whether a leading tab
is present in a section heading.

1c8b925a87 Live local variables are being dropped because the begin or end labels marking 
their scope are being deleted.  Workaround is to widen scope to full function.

4328919c08 Fixed some spiller bugs exposed by the recent two-address code changes. Now 
there may be other def(s) apart from the use&def two-address operand. We need
to check if the register reuse for a use&def operand may conflicts with another
def. Provide a mean to recover from the conflict if it is detected when the
defs are processed later.

4bafa71dc1 For PR786: 
Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

14437996b7 General clean up of teh dwarf writer. 
1. Most significant is the folding of debug information entries.  This
reduced self hosted -g SelectionDAGISel.s from 120M to 13M and pretty
close to matching .o file sizes with gcc.

2. Debug information entry printing for debugging the dwarf code.

3. Bring all the code closer to llvm standards.

4. Misc. fixes and doc clean ups.

35cd439221 Allow the getRegForInlineAsmConstraint method to return a register class with 
no fixes physreg.  Treat this as permission to use any register in the register
class.  When this happens and it is safe, allow the llvm register allcoator to
allocate the register instead of doing it at isel time.  This eliminates a ton
of copies around common inline asms.  For example:

int test2(int Y, int X) {
  asm("foo %0, %1" : "=r"(X): "r"(X));
  return X;
}

now compiles to:

_test2:
        foo r3, r4
        blr

instead of:

_test2:
        mr r2, r4
        foo r2, r2
        mr r3, r2
        blr

GCC produces:

_test2:
        foo r4, r4
        mr r3,r4
        blr

f20968bc33 give branch folding a simple heuristic to decide which block to split so that 
it inserts an uncond branch where it is less likely to cause a problem.  This

e6ba8a819c 1. Clean up code due to changes in SwitchTo*Section(2) 
2. Added partial debug support for mingw\cygwin targets (the same as
   Linux\ELF). Please note, that currently mingw\cygwin uses 'stabs' format
   for storing debug info by default, thus many (runtime) libraries has
   this information included. These formats shouldn't be mixed in one binary
   ('stabs' & 'DWARF'), otherwise binutils tools will be confused.
