12cf8ddaea eliminateFrameIndex() is even more complicated if frame ptr is used instead of SP when there are dynamic alloca's.

430c9217f0 redesign the primary datastructure used by mem2reg to eliminate an 
std::map of std::vector's (ouch!).  This speeds up mem2reg by 10% on 176.gcc.

tombstones, causing subsequent insertions to infinitely loop.

dc0a9a7b4a 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.

a79819d8c6 Implement the NO_INSTALL feature. Setting this variable to any value in 
a directory's Makefile will prevent the build products from that directory
from being installed. This is useful for tools and libraries that are
only useful as part of the build process.

dac63788ab 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.

650d0672f7 - Store val, [sp, c] must be selected to tSTRsp. 
- If c does not fit in the offset field, materialize sp + c into a register
  using tADDhirr.

92b50800f6 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.

c85e79f3e0 With the last change, we no longer need both directions of mapping from 
BBNumbers.  Instead of using a bi-directional mapping, just use a single
densemap.  This speeds up mem2reg on 176.gcc by 8%, from  1.3489 to
1.2485s.

557ab15e71 Apply the VISIBILITY_HIDDEN field to the remaining anonymous classes in 
the Transforms library. This reduces debug library size by 132 KB, debug
binary size by 376 KB, and reduces link time for llvm tools slightly.
