d39ae2fa6d Add a helper class (APSInt) which can represent an APInt along with sign 
information.  This is useful when a value does have a sign associated with
it.  This shouldn't be used generally in LLVM for mid-level optimizer stuff.

go to the same destination. Now we're producing really good code for
switch-lower-feature.ll testcase

419396d2fe For PR1297: 
Implement bswap, ctpop, ctlz, and cttz utilizing the new overloaded
intrinsic feature of tblgen. By defining llvm_int_ty to have an ValueType
of iAny, any intrinsic using that type becomes an overloaded intrinsic.
This signals that a) any integer type could be used for that argument and
b) the intrinsic needs a suffix to match each such argument for the
actual intrinsic.

5ac41f7bc9 For PR1297: 
Intrinsic functions might need to be generated (if they are overloaded) so
returning a const char* is no longer possible. Change getOperationName to
return a std::string instead.

e1b0aae7c7 For PR1297: 
Change the interface to the getName, getType, getDeclaration methods to
include the "actual" types of the result/arguments. This is necessary to
support overloaded intrinsics.

f4ea8f8a73 For PR1297:

bit width. This is used for intrinsics overloading on integer type.

4269ae1274 For PR789:

fc67ef7cfe For PR789: 
* Add a method: bool isAbsolute() const, which determines if the path name

a42484728c Add support for the v1i64 type. This makes better code for this: 
#include <mmintrin.h>

extern __m64 C;

void baz(__v2si *A, __v2si *B)
{
  *A = C;
  _mm_empty();
}

We get this:

_baz:
        call "L1$pb"
"L1$pb":
        popl %eax
        movl L_C$non_lazy_ptr-"L1$pb"(%eax), %eax
        movq (%eax), %mm0
        movl 4(%esp), %eax
        movq %mm0, (%eax)
        emms
        ret

GCC gives us this:

_baz:
        pushl   %ebx
        call    L3
"L00000000001$pb":
L3:
        popl    %ebx
        subl    $8, %esp
        movl    L_C$non_lazy_ptr-"L00000000001$pb"(%ebx), %eax
        movl    (%eax), %edx
        movl    4(%eax), %ecx
        movl    16(%esp), %eax
        movl    %edx, (%eax)
        movl    %ecx, 4(%eax)
        emms
        addl    $8, %esp
        popl    %ebx
        ret

cc91b2a91d Start value symbol tables out small (space for 16 elts), not huge (space for 512). 
This is particularly useful for the JIT, which lazily deserializes functions.

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
