This reverts commit 8b75e6bc35.

The FileCheck tests are not equivalent:

1d46732281 Fix RegisterCoalescer::rematerializeTrivialDef() so that it works on flipped 
CoalescerPairs. Also, make it take a CoalescerPair directly like other methods
of RegisterCoalescer.

c5f147459b Fix some issues with rematerialization in RegisterCoalescer when the destination 
of the copy is a subregister def. The current code assumes that it can do a full
def of the destination register, but it is not checking that the def operand is
read-undef. It also doesn't clear the subregister index of the destination in
the new instruction to reflect the full subregister def.

These issues were found running 'make check' with my next commit that enables
rematerialization in more cases.

382a5530ec Don't asume that a static function in an extern "C" block will not be mangled. 
Since functions with internal linkage don't have language linkage, it is valid
to overload them:

extern "C" {
       static int foo();
       static int foo(int);
}

So we mangle them.

17fe48ce6e Retain the name of the new internal global that's been shrunk. 
It's possible (e.g. after an LTO build) that an internal global may be used for
debugging purposes. If that's the case appending a '.b' to it makes it hard to
find that variable. Steal the name from the old GV before deleting it so that
they can find that variable again.

6b9d461780 For Mips 16, add the optimization where the 16 bit form of addiu sp can be used 
if the offset fits in 11 bits. This makes use of the fact that the abi
requires sp to be 8 byte aligned so the actual offset can fit in 8
bits. It will be shifted left and sign extended before being actually used.
The assembler or direct object emitter will shift right the 11 bit
signed field by 3 bits. We don't need to deal with that here.

f09e02f01a X86: Disable generation of rep;movsl when %esi is used as a base pointer. 
This happens when there is both stack realignment and a dynamic alloca in the
function. If we overwrite %esi (rep;movsl uses fixed registers) we'll lose the
base pointer and the next register spill will write into oblivion.

Fixes PR15249 and unbreaks firefox on i386/freebsd. Mozilla uses dynamic allocas
and freebsd a 4 byte stack alignment.

4be3853fd0 Debug Info: LiveDebugVarible can remove DBG_VALUEs, make sure we emit them back. 
RegisterCoalescer used to depend on LiveDebugVariable. LDV removes DBG_VALUEs
without emitting them at the end.

We fix this by removing LDV from RegisterCoalescer. Also add an assertion to
make sure we call emitDebugValues if DBG_VALUEs are removed at
runOnMachineFunction.
