afc9a0c6b0 VMCore: Add Type::getIntN[Ptr]Ty, which are the obvious generic forms of
Type::getInt{1,8,...}[Ptr]Ty, so code can consistently use the methods on Type
without occasionally needed to call IntegerType::get.

18d57661f3 Build system fix to make llvm-mc properly build

mechanism to ensure that PARALLEL_DIRS get built
after DIRS.

6ab10f69a9 Add fast paths to ScalarEvolution::getSizeOf and getOffsetOf, as
they're used a lot by getNodeForGEP, which can be called a lot.
This speeds up -iv-users by around 15% on several testcases.

2aae6ae572 Micro-optimization:
If we have this situation:

    jCC  L1
    jmp  L2
L1:
  ...
L2:
  ...

We can get a small performance boost by emitting this instead:

    jnCC L2
L1:
  ...
L2:
  ...

This testcase shows an example of this:

float func(float x, float y) {
    double product = (double)x * y;
    if (product == 0.0)
        return product;
    return product - 1.0;
}

2fb938fd42 Build system fixes. llvm-mc depends on
libEnhancedDisassembly, so we now build the
static library in all cases (although the shared
library is only built when requested/possible).

Also, fixed a bug where edis wasn't properly
initializing the targets it uses.

ca9b7037e2 Suppress LinearFunctionTestReplace when the computed backedge-taken
expression is a UDiv and it doesn't appear that the UDiv came from
the user's source.

ScalarEvolution has recently figured out how to compute a tripcount
expression for the inner loop in
SingleSource/Benchmarks/Shootout/sieve.c, using a udiv. Emitting a
udiv instruction dramatically slows down the enclosing loop.

668b15467b Second try at integrating the edis tester. This
time I use the LIBS variable, which is not subject
to a %.a -> -l% transformation, to link llvm-mc
against libEnhancedDisassembly.

llvm-mc -edis works the same as llvm-mc
-disassemble, but outputs tokens and operands.

bb6e9d8cf7 Fixed a crasher in arm disassembler within ARMInstPrinter.cpp after calling
ARM_AM::getSoImmVal(V) with a legitimate so_imm value: #245 rotate right by 2.
Introduce ARM_AM::getSOImmValOneOrNoRotate(unsigned Arg) which is called from
ARMInstPrinter.cpp's printSOImm() function, replacing ARM_AM::getSOImmVal(V).

  for (i=0;i<n;++i)

the loop, and eliminate the if.
