9cbc3fb1ab Revert the earlier change that removed the M_REMATERIALIZABLE machine 
instruction flag, and use the flag along with a virtual member function
hook for targets to override if there are instructions that are only
trivially rematerializable with specific operands (i.e. constant pool
loads).

b60d8a92c9 Replace M_REMATERIALIZIBLE and the newly-added isOtherReMaterializableLoad 
with a general target hook to identify rematerializable instructions. Some
instructions are only rematerializable with specific operands, such as loads
from constant pools, while others are always rematerializable. This hook
allows both to be identified as being rematerializable with the same
mechanism.

31622dd4a9 The Intrinsic::getDeclaration function's Tys parameter only contains the 
types of the iAny types involved in the overloaded intrinsic. Thus, we
can't use the argument number as the index but have to count them separately
in order to index Tys correctly. This patch rectifies this situation.

dc82c5a195 Add an "implies" field to features. This indicates that, if the current 
feature is set, then the features in the implied list should be set also.
The opposite is also enforced: if a feature in the implied list isn't set,
then the feature that owns that implies list shouldn't be set either.

f12ab5a55b For PR1328: 
Don't assert everytime an intrinsic name isn't recognized. Instead, make
the assert optional when callin getIntrinsicID(). This allows the assembler
to handle invalid intrinsic names gracefully.

fcebed346e Prepare for Subversion migration by implementing a -usesvn to tell the 
script to to check out llvm and llvm-test from Subversion instead of CVS.
Without this option the script will continue to check out from CVS. To
specify the Subversion URL, set the SVNURL environment variable or pass
-svnurl followed by the URL. For now, -svnurl will default to Reid's
temporary (read-only, daily snapshot) SVN server. Try it out if you like!

5b8b959d29 For PR1297: 
Implement code generation for overloaded intrinsic functions. The basic
difference is that "actual" argument types must be provided when
constructing intrinsic names and types. Also, for recognition, only the
prefix is examined. If it matches, the suffix is assumed to match. The
suffix is checked by the Verifier, however.

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
