don't get accepted by LLVM accidentally. Adjust the supporting test cases

When moving constant entries in 'Map' if the entry is the representative
constant for the abstractypemap, make sure to update it as well. This
fixes the bcreader failures from last night on several C++ apps.

For large constants (e.g. arrays and structs with many elements) just
...
creating the keys and doing comparisons to index into 'Map' takes a lot
of time. For these large constants, keep an inverse map so that 'remove'
and move operations are much faster.
This speeds up a release build of the bc reader on Eric's nasty python
bytecode file from 1:39 to 1:00s.

Change ConstantArray::replaceUsesOfWithOnConstant to attempt to update
...
constant arrays in place instead of reallocating them and replaceAllUsesOf'ing
the result. This speeds up a release build of the bcreader from:
136.987u 120.866s 4:24.38
to
49.790u 49.890s 1:40.14
... a 2.6x speedup parsing a large python bc file.

Split SimpleConstantVal up into its components, so each Constant subclass getsa different enum value. This allows 'classof' for these to be really simple,not needing to call getType() anymore.
...
This speeds up isa/dyncast/etc for constants, and also makes them smaller.
For example, the text section of a release build of InstCombine.cpp shrinks
from 230037 bytes to 216363 bytes, a 6% reduction.
