b867746a05 Clarify the requirements for a "tail call" to actually be optimized into a 
jump.  People clearly weren't finding the extra requirements in
CodeGenerator.html.

31e39bd3d4 Update docs for bitcode changes. For object size checking we won't 
work with partial objects so just count the type as a boolean. Update
appropriately.

a381effe72 add the ability for TargetData to return information about legal integer 
datatypes on a given CPU.  This is intended to allow instcombine and other
transformations to avoid converting big sequences of operations to an
inconvenient width, and will help clean up after SRoA.  See also "Adding 
legal integer sizes to TargetData" on Feb 1, 2009 on llvmdev, and PR3451.

Comments welcome.

aa99c94e2a Revert 85678/85680. The decision is to stay with the current form of 
indirectbr, thus we don't need "blockaddr(@func, null)".  Eliminate it
for simplicity.

b2c0e243c5 Make blockaddress(@func, null) be valid, and make 'deleting a basic 
block with a blockaddress still referring to it' replace the invalid 
blockaddress with a new blockaddress(@func, null) instead of a 
inttoptr(1).

This changes the bitcode encoding format, and still needs codegen 
support (this should produce a non-zero value, referring to the entry
block of the function would also be quite reasonable).

used to support GlobalVariables storing MDNodes, back when they were derived
from Constant before the introduction of NamedMDNode, but never removed.

84a1eeb7ed Move the integer type out of 'derived' and into 'primitive'. This permits us 
to explain that derived types are all composed of other types, which primitive
types aren't. Without moving integer out of derived, this wouldn't be true.

Perform a few trivial cleanups; 'i1' went from a link to #t_primitive to
#t_integer (a holdover from when it was a bool type I suppose).

a function ("inline" keyword).  No functional change
