Clarify getRelocationAddress x getRelocationOffset a bit.

getRelocationAddress is for dynamic libraries and executables,
getRelocationOffset for relocatable objects.

Mark the getRelocationAddress of COFF and MachO as not implemented yet. Add a
test of ELF's. llvm-readobj -r now prints the same values as readelf -r.

Use a pointer as the relocation iterator.

Since the relocation iterator walks only the relocations in one section, we
can just use a pointer and avoid fetching information about the section at
every reference.

[inline asm] Add a test case for r180226.  The specific issue is that the inline

This patch adds the X86FixupLEAs pass, which will reduce instruction
latency for certain models of the Intel Atom family, by converting
instructions into their equivalent LEA instructions, when it is both
useful and possible to do so.

Remove SMLoc paired with CHECK-NOT patterns. Not functionality change.

Pattern has source location by itself. After adding a trivial method to
retrieve it, it's unnecessary to pair a source location for CHECK-NOT patterns.
One thing revised after this is the diagnostic info is more accurate by
pointing to the start of the CHECK-NOT pattern instead of the end of the
CHECK-NOT pattern. E.g. diagnostic message previously looks like

    <stdin>:1:1: error: CHECK-NOT: string occurred!
    test
    ^
    test.txt:1:16: note: CHECK-NOT: pattern specified here
    CHECK-NOT: test
                   ^

is changed to

    <stdin>:1:1: error: CHECK-NOT: string occurred!
    test
    ^
    test.txt:1:12: note: CHECK-NOT: pattern specified here
    CHECK-NOT: test
               ^

Mips assembler: .set reorder support

Mips have delayslots for certain instructions 
like jumps and branches. These are instructions 
that follow the branch or jump and are executed
before the jump or branch is completed.

Early Mips compilers could not cope with delayslots
and left them up to the assembler. The assembler would
fill the delayslots with the appropriate instruction,
usually just a nop to allow correct runtime behavior.

The default behavior for this is set with .set reorder.
To tell the assembler that you don't want it to mess with
the delayslot one used .set noreorder.

For backwards compatibility we need to support
.set reorder and have it be the default behavior in the 
assembler.

Our support for it is to insert a NOP directly after an
instruction with a delayslot when in .set reorder mode.
