be0b356593 PR466: 
* Make the linker find lib*.bca files now instead of lib*.bc since those
  are what the makefiles now generate for bytecode archives.
* Make sure the linker only links archives when LinkLibraries is called.
  Previously if it found a lib*.bc file and that file was a bytecode file,
  it would link in the entire bytecode. This could make -lc -lc fail with
  duplicate symbols error but it shouldn't as searching multiple libraries,
  even the same one more than once, is permitted.
* Now that the above problems are corrected, implement the dependent libs
  feature. After the module is linked with all specified libraries, the
  LinkLibraries function will obtain the set of dependent libraries from
  the linked modules and attemp to find and link against those libraries.

0284628e8e Fix several bugs in 'op x, imm' handling. Foremost is that we now emit 
addi r3, r3, -1
instead of

Secondarily, this fixes several cases where we could crash given an unsigned
constant.  And fixes a couple of minor missed optimization cases, such as
xor X, ~0U -> not X

37dc938bbe If we have something like this: 
if (x) {
    code
    ...
  } else {
    code
    ...
  }

Turn it into:

  code
  if (x) {
    ...
  } else {
    ...
  }

This reduces code size and in some common cases allows us to completely
eliminate the conditional.  This turns several if/then/else blocks in loops
into straightline code in 179.art, turning the loops into single basic blocks
(good for modsched even!).

Maybe now brg will leave me alone ;-)

928b47ae2e Revamp long/ulong comparisons to use a much more efficient sequence (thanks 
to Brian and the Sun compiler for pointing out that the obvious works :)

This also enables folding all long comparisons into setcc and branch
instructions: before we could only do == and !=

For example, for:
void test(unsigned long long A, unsigned long long B) {
   if (A < B) foo();
 }

We now generate:

test:
        subl $4, %esp
        movl %esi, (%esp)
        movl 8(%esp), %eax
        movl 12(%esp), %ecx
        movl 16(%esp), %edx
        movl 20(%esp), %esi
        subl %edx, %eax
        sbbl %esi, %ecx
        jae .LBBtest_2  # UnifiedReturnBlock
.LBBtest_1:     # then
        call foo
        movl (%esp), %esi
        addl $4, %esp
        ret
.LBBtest_2:     # UnifiedReturnBlock
        movl (%esp), %esi
        addl $4, %esp
        ret

Instead of:

test:
        subl $12, %esp
        movl %esi, 8(%esp)
        movl %ebx, 4(%esp)
        movl 16(%esp), %eax
        movl 20(%esp), %ecx
        movl 24(%esp), %edx
        movl 28(%esp), %esi
        cmpl %edx, %eax
        setb %al
        cmpl %esi, %ecx
        setb %bl
        cmove %ax, %bx
        testb %bl, %bl
        je .LBBtest_2   # UnifiedReturnBlock
.LBBtest_1:     # then
        call foo
        movl 4(%esp), %ebx
        movl 8(%esp), %esi
        addl $12, %esp
        ret
.LBBtest_2:     # UnifiedReturnBlock
        movl 4(%esp), %ebx
        movl 8(%esp), %esi
        addl $12, %esp
