Fix a very bad typo.  Since the register number was off by one, the ARM
load/store optimizer would incorrectly think that registers D26 and D28
were consecutive and would generate a VLDM instruction to load them.
The assembler was not convinced.

Clear the SCEVExpander's insertion point after making deletions,
so that the SCEVExpander doesn't retain a dangling pointer as its
insert position. The dangling pointer in this case wasn't ever used
to insert new instructions, but it was causing trouble with
SCEVExpander's code for automatically advancing its insert position
past debug intrinsics.

This fixes use-after-free errors that valgrind noticed in
test/Transforms/IndVarSimplify/2007-06-06-DeleteDanglesPtr.ll and
test/Transforms/IndVarSimplify/exit_value_tests.ll.

If call result is in ST0 and it is not being passed to the caller's
caller, then it is not safe to optimize the call into a sibcall since
the call result has to be popped off the x87 stack.

Revert r98679.  The disassembler will be updated to depend on the existence of
IndexModeUpd and then populates the Inst{21}=1 while populating the instructions
for disassembly.

Fix more places to more thoroughly ignore debug intrinsics. This fixes
use-before-def errors in SCEVExpander-produced code in sqlite3 when debug
info with optimization is enabled, though the testcases for this are

major surgery on tblgen: generalize TreePatternNode
to maintain a list of types (one for each result of
the node) instead of a single type.  There are liberal
hacks added to emulate the old behavior in various
situations, but they can start disolving now.

Force configuration of some projects before others.  In particular, some
projects rely upon llvm-gcc, the LLVM test suite, and poolalloc.  This ensures
that the aforementioned projects have their object trees created first so that
other projects can find their object trees when they themselves are configured.

Fixed the encoding problems of the crc32 instructions. All had the Operand size
override prefix and only the r/m16 forms should have had that.  Also for variant
one, the AT&T syntax, added suffixes to all forms.  Also added the missing
64-bit form for 'CRC32 r64, r/m8'.  Plus added test cases for all forms and
tweaked one test case to add the needed suffixes.
