14b0529532 Add support alignment of allocation instructions. 
Add support for specifying alignment and size of setjmp jmpbufs.

No targets currently do anything with this information, nor is it presrved
in the bytecode representation.  That's coming up next.

a1e3f54396 refactor a bit of code. 
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.

23ec01fcc3 Minor speedup to avoid array searches given a Use*. This speeds up bc reading 
of the python test from 1:00 to 54s.

d0ff1adbdb Change the signature of replaceUsesOfWithOnConstant. The bool was always 
true dynamically.  Finally, pass the Use* that replaceAllUsesWith has into
the method for future use.

a55b30a225 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.

cea141f1d1 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.

df0ef1d0fe 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.

1325b42a7d Now that hasConstantValue is more careful w.r.t. returning values that only 
dominate the PHI node, this code can go away.  This also makes passes more

b3b48e11da Use the bool argument to hasConstantValue to decide whether the client is 
prepared to deal with return values that do not dominate the PHI.  If we
cannot prove that the result dominates the PHI node, do not return it if
the client can't cope.
