Dan Gohman c74bc28297 The inbounds keyword isn't relevant to overindexing of
static array types. Thanks to Duncan for pointing this out!

Dan Gohman 66c4d61010 Remove the "special case" for zero-length arrays, and rephrase this
paragraph to be more precise.

Chris Lattner 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.

Chris Lattner 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.

Chris Lattner 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).

Chris Lattner 3ed871fe62 add enough support for indirect branch for the feature test to pass
(assembler,asmprinter, bc reader+writer) and document it.  Codegen
currently aborts on it.

Nick Lewycky 93e06a57c9 Remove the "metadata*" type and simplify the code it complicated. This was only
used to support GlobalVariables storing MDNodes, back when they were derived
from Constant before the introduction of NamedMDNode, but never removed.

Nick Lewycky 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).

Dale Johannesen 2aaf539564 Add an 'inline hint' attribute to represent source
code hints that it would be a good idea to inline
a function ("inline" keyword).  No functional change
yet; FEs do not emit this and inliner does not use it.

Dan Gohman 2de532c132 Clarify a few things in the inbounds description.
Describing inbounds in terms of infinitely precise arithmetic prohibits
the assumption address-space-sized integer arithmetic will wrap, with
a wrapped-around value landing within the same object.
