ea857029ea Remove ImmediateDominator analysis. The same information can be obtained from DomTree. A lot of code for 
constructing ImmediateDominator is now folded into DomTree construction.

This is part of the ongoing work for PR217.

135f2f1261 Chris convinced me that the default size of the SmallVector (2) was too 
small.  Since it doesn't cost much to have 2 more (8 bytes), but not having
them would require a malloc as soon as the third one is needed. Setting
the default to 4 delays the malloc until the 5th parameter attribute.

0160bf7114 rearchitect the registration mechanism used by the command line option stuff. 
This dramatically reduce the amount of memory allocated by the commandline stuff
at static init time, changing it to build local data structures when ParseCommandLineOptions
is called.  In a dummy empty program that links some llvm libraries, this reduces
the number of malloc'd bytes from 4864 to 3360 on entry to main.  Most of that
memory is now allocated by non-commandline related stuff.

Implement bswap, ctpop, ctlz, and cttz utilizing the new overloaded
intrinsic feature of tblgen. By defining llvm_int_ty to have an ValueType

actual intrinsic.

#include <mmintrin.h>

extern __m64 C;

void baz(__v2si *A, __v2si *B)
{

  _mm_empty();
}

We get this:

_baz:

"L1$pb":
        popl %eax
        movl L_C$non_lazy_ptr-"L1$pb"(%eax), %eax

        movl 4(%esp), %eax
        movq %mm0, (%eax)
        emms
        ret

GCC gives us this:

_baz:
        pushl   %ebx
        call    L3
"L00000000001$pb":
L3:

4984ab6c01 Compute getLowBitsSet correctly. Using the complement of a 64-bit value 
and shifting down without regard for the bitwidth of the APInt can lead
to incorrect initialization values. Instead, check for the word size case
(to avoid undef results from shift) and then do (1 << loBitsSet) - 1

16d08887ef Actually, for getHighBitsSet and getLowBitsSet, don't make a 0 bit size 
illegal. Instead do the 0 valued construction for the user. This is because
the caller may not know (or care to check) that the number of bits set is
zero.

d24dc1f9a6 Make it illegal to set 0 bits in getHighBitsSet and getLowBitsSet. For that 
they should have used the uint64_t constructor. This avoids causing
undefined results via shifts by the word size when the bit width is an
exact multiple of the word size.

fb188ea881 In the getBitsSet function, don't optimize for a common case that is 
already covered by getLowBitsSet (i.e. when loBits==0). Consequently, remove
the default value for loBits and reorder the arguments to the more natural
loBits, hiBits order. This makes it more clear that this function is for bit
groups in the middle of the bit width and not towards one end or the other.
