f514e2d28f Make the Interpreter use libffi if it's available. Patch from Alexei Svitkine!
This requires a rebuild of 'configure' itself. I will be committing that next, but
built with the wrong version of autoconf. Somebody who has the right one, please update
it.

As a side-note, because of the way autoconf works, all built tools will link against
libffi, not just lli. If you know how to fix this, please let me know ...

c533612949 Remove SDNode's virtual destructor. This makes it impossible for
SDNode subclasses to keep state that requires non-trivial
destructors, however it was already effectively impossible,
since the destructor isn't actually ever called. There currently
aren't any SDNode subclasses affected by this, and in general
it's desireable to keep SDNode objects light-weight.

This eliminates the last virtual member function in the SDNode
class, so it eliminates the need for a vtable pointer, making
SDNode smaller.

dbe664adcd Fix SelectionDAG::ReplaceAllUsesWith to behave correctly when
uses are added to the From node while it is processing From's
use list, because of automatic local CSE. The fix is to avoid

a RAUW call, the From node has no users and may be deleted.

1999ff1d81 Port this test from dejagnu to unit testing.
The way this worked before was to test APInt by running
"lli -force-interpreter=true" knowing the lli uses APInt under the hood to
store its values. Now, we test APInt directly.

50c3dfefd9 Minor tweak to LowerUINT_TO_FP_i32. Bias (after scalar_to_vector) has two uses so we should make it the second source operand of ISD::OR so 2-address pass won't have to be smart about commuting.
%reg1024<def> = MOVSDrm %reg0, 1, %reg0, <cp#0>, Mem:LD(8,8) [ConstantPool + 0]
%reg1025<def> = MOVSD2PDrr %reg1024
%reg1026<def> = MOVDI2PDIrm <fi#-1>, 1, %reg0, 0, Mem:LD(4,16) [FixedStack-1 + 0]
%reg1027<def> = ORPSrr %reg1025<kill>, %reg1026<kill>

The reason 2-addr pass isn't smart enough to commute the ORPSrr is because it can't look pass the MOVSD2PDrr instruction.

0b6679d32f Fix copy and pasted typos that prevented strtok_r, realloc, getenv, ungetc,
putc, puts, perror, vscanf and vsscanf from getting annotations.

Add annotations for eight printf functions, memalign, pread and pwrite.

On Linux, llvm-gcc sometimes renames strdup, getc, putc, strtok_r, scanf and
sscanf. Match the alternate function names.

Fix a crash annotating opendir.

Don't mark fsetpos's second parameter as nocapture. It's supposed to be
captured.

Do mark fopen's path and mode strings as nocapture. Mark ferror as readonly,
but not fileno which may set errno.
