Patch by John Tytgat!

llvm-svn: 99096

with changes to add a separate optional register update argument.  Change all
the NEON instructions with address register writeback to use it.

llvm-svn: 99095

address register writeback.

rewrite the existing VST3 and VST4 instructions to use the same classes as
the others.

writeback, and refactor the existing double-spaced VST2 instructions.
These are only for the disassembler since codegen doesn't use them, at
least for now.

instead of {g|s}etOperand(0).

load/stores with address register writeback, and use "odd" suffix to distinguish
instructions to access odd numbered registers (instead of "a" and "b").
No functional changes.

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.

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.

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.

disabled for several months (since svn r88806) and no one noticed.  My fix
for pr6543 yesterday reenabled it, but broke the ARM port's code for using
TBB/TBH.  Rather than adding a target hook to disable merging for Thumb2 only,
I'm just taking this out.  It is not common to have identical jump tables,
the code we used to merge them was O(N^2), and it only helps code size, not
performance.

 - This is "extraordinarily" Darwin 'as' compatible. See the litany of FIXMEs littered about for more information.
 - There are a few cases which seem to clearly be 'as' bugs which I have left unsupported, and there is one cases where we diverge but should fix if it blocks diffing .o files (Darwin 'as' ends up widening a jump unnecessarily).
 - 403.gcc build, runs, and diffs equivalently to the 'as' built version now (using llvm-mc). However, it builds so slowly that I wouldn't recommend trying it quite yet. :)
