3cfc1d22b2 Fix Transforms/DeadArgElim/2007-02-07-FuncRename.ll, fallout from PR411. 
This happened because deadargelim now causes VMCore to auto-rename every
function that it hacks arguments out of.  Because it hacks arguments out of
functions in a non-deterministic order, this caused the resultant numbering
to be nondet.  The fix is to just be careful to not rename functions!

8bed6c968f In thumb mode, R3 is reserved, but it can be live in to the function. If 
that is the case, whenever we use it as a scratch register, save it to R12
first and then restore it after the use.
This is a temporary and truly horrible workaround!

7142f8755a - If fp (r7) is used to reference stack objects, use [r, r] address mode.

  using r7 - offset.
- Other bug fixes.

c67da0cf13 Two fixes: 
1. Memset takes an i32 for the value to set, not i8.  This was causing GCC to
   ICE all over the place (PR1183).
2. memcpy/memmove were not properly zext/trunc'ing the size in some cases.

fd43dcfc57 Add a class APInt to represent arbitrary precision constant integral values. 
It is a functional replacement for common case integer type like "unsigned",
"uint64_t", but also allows non-byte-width integer type and large integer
value types such as 3-bits, 15-bits, or more than 64-bits of precision. For
more details, see pr1043.

d2a988caad Although targets are not required to support integers > 64bits, TargetData 
must in order for backends that do want to support large integer types to be
able to function. Consequently, don't assert if the bitwidth > 64 bits
when computing the size and alignment. Instead, compute the size by rounding
up to the next even number of bytes for the size. Compute the alignment
as the same as the LongABIAlignment. These provide reasonable defaults
that the target can override.

d3874049a5 With the last change, we no longer need both directions of mapping from
