fe7a46c1e1 Fix a fixme by correctly calculating preferred alignments for functions, 
based on the alignment of the symbol and the target data's preferred align
for that type.

Also, rename some arguments for consistency.

bdde131dac Eliminate the O(n) version of TypeSymbolTable::remove, it is dead. When 
inserting a type into the type symbol table, only compute unique name if not
in symtab already.

d69c837c73 Eliminate a bunch of work from ValueSymbolTable::insert for the common case 
where a symbol name doesn't conflict.  This speeds up bc reading 16% on 176.gcc!

c0fcd78ca0 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.

38185b79da 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.

677cc21b01 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.

c4ba711e91 - 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.

4881e131eb 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.

5fee493a8c 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.

8749d297f5 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.
