f4d7708972 Make SmallVector's grow use memcpy in common cases 
instead of std::uninitialized_copy, which uses memmove.

8eab8a2798 Remove some DAG combiner assumptions about sizes 
of integer types.  Fix the isMask APInt method to
actually work (hopefully) rather than crashing
because it adds apints of different bitwidths.
It looks like isShiftedMask is also broken, but
I'm leaving that one to the APInt people (it is
not used anywhere).

b606dba13b Remove the SmallVector ctor that converts from a SmallVectorImpl. This 
conversion open the door for many nasty implicit conversion issues, and
can be easily solved by initializing with (V.begin(), V.end()) when 
needed.

This patch includes many small cleanups for sdisel also.

2896652be2 when a node is removed from an ilist, set its next/prev pointers to 
null.  This means that uses of invalidated iterators will explode violently
with:
ilist:143: failed assertion `NodePtr && "++'d off the end of an ilist!"'

instead of happening to work "most of the time".

0123b7dcfa Make tblgen a little smarter about constants smaller than i32. Currently, 
tblgen will complain if a sign-extended constant does not fit into a
data type smaller than i32, e.g., i16. This causes a problem when certain
hex constants are used, such as 0xff for byte masks or immediate xor
values.

tblgen will try the sign-extended value first and, if the sign extended
value would overflow, it tries to see if the unsigned value will fit.
Consequently, a software developer can now safely incant:

	(XORHIr16 R16C:$rA, 0xffff)

which is somewhat clearer and more informative than incanting:

	(XORHIr16 R16C:$rA, (i16 -1))

even if the two are bitwise equivalent.

Tblgen also outputs the 64-bit unsigned constant in the generated ISel code
when getTargetConstant() is invoked.

95da16e288 Changed profiling method for ImmutableMap to once again just use its 
unique ImutAVLTree* for profiling.

Modified ImutAVLTree:
 (1) changed ComputeHash() to ComputeDigest() and
 (2) changed Profile() to use the computed digest and
 (3) modified insertion of IMutAVLTree into the FoldingSet owned by
     the ImutAVLTreeFactory object to use profiling instead of computing
     a direct hash.  This fixes a bug where our abuse of the FoldingSet would
     not work when the FoldingSet was resized.

f357afb404 Modified node creation of ImutAVLTree to do a hash lookup for an existing 
node in the FoldingSet of nodes held by the Factory object.  If we
we find a node with a matching hash, we do a full structural comparison.
Nodes are also now inserted into the FoldingSet only when we mark them
Immutable, as their children can change during intermediate-rebalancing.

The 'Profile' method for ImutAVLTree is no longer used when looking up
existing ImutAVLTrees with a given set of contents; instead the Profile method
is used by other clients that wish to insert such a tree into a folding set.
This means that we are not using FoldingSet in ImutAVLTreeFactory in the way
it was intended, but instead are using it as an opaque hashtable.

cadf873c83 Added additional overloaded operators for APSInt to match the operators of 
APInt.

While some operators were already specifically overloaded for APSInt, others
resulted in using the overloaded operator methods in APInt, which would result
in the signedness bit being lost.

Modified the APSInt(APInt&) constructor to be "explicit" and to take an
extra (optional) flag to indicate the signedness.  Making the ctor explicit
will catch any implicit conversations between APSInt -> APInt -> APSInt that
results in the signedness flag being lost.

6518f5fcbf Replaced (FoldingSet) profiling of ImutAVLTree with a hashing based scheme. The 
problem was that we previously hashed based on the pointers of the left and
right children, but this is bogus: we can easily have different trees that
represent the same set. Now we use a hashing based scheme that compares the
*contents* of the trees, but not without having to do a full scan of a tree. The
only caveat is that with hashing is that we may have collisions, which result in
two different trees being falsely labeled as equivalent. If this becomes a
problem, we can add extra data to the profile to hopefully resolve most
collisions.

a753f703d1 Made 'profiling' of objects in a FoldingSet trait-based using FoldingSetTrait 
instead of always assuming that the stored objects had a method called
'Profile'. The default behavior is to dispatch to a 'Profile' method (as
before), but via template specialization this behavior can now be overridden by
clients.

Added templated class 'FoldingSetNodeWrapper', a generic wrapper class that
allows one to insert objects into a FoldingSet that do not directly inherit from
FoldingSetNode. This is useful for inserting objects that do not always need to
pay the overhead of inheriting from FoldingSetNode, or were designed with that
behavior in mind.

returning an iterator if the user just wants to find the value of a key).

e509e7a178 Implemented "FIXME" in ImutAVLTree: isEqual() now also compares the *data* value 
and not just the key value when comparing trees. To do this we added data_type
and data_type_ref to the ImutContainerInfo trait classes. For values stored in
the tree that do not have separate key and data components, data_type is simply
a typedef of bool, and isDataEqual() always evaluates to true. This allows us to
support both ImmutableSet and ImmutableMap using the same underlying logic.

ee7ae384f5 When converting to integer, do bit manipulations in the destination 
memory rather than in a copy of the APFloat.  This avoids problems
when the destination is wider than our significand and is cleaner.

Also provide deterministic values in all cases where conversion
fails, namely zero for NaNs and the minimal or maximal value
respectively for underflow or overflow.

aef806e9cb Added typedef "value_type" to DenseMap (similar typedef appears in std::map). 
Added method FindAndConstruct() to DenseMap, which does the same thing as
operator[], except that it refers value_type& (a reference to both the
key and mapped data pair).  This method is useful for clients that wish
to access the stored key value, as opposed to the key used to do the
actual lookup (these need not always be the same).

Redefined operator[] to use FindAndConstruct() (same logic).

33bbed8f2a Added implementation of immutable (functional) maps and sets, as 
implemented on top of a functional AVL tree.  The AVL balancing code
is inspired by the OCaml implementation of Map, which also uses a functional
AVL tree.

Documentation is currently limited and cleanups are planned, but this code
compiles and has been tested.

68e53ad6cb Add a new function tcExtract for extracting a bignum from an 
arbitrary range of bits embedded in the middle of another bignum.
This kind of operation is desirable in many cases of software
floating point, e.g. converting bignum integers to floating point
numbers of fixed precision (you want to extract the precision most
significant bits).

Elsewhere, add an assertion, and exit the shift functions early if
the shift count is zero.

6de84985a4 improve iplist comments. Switch iplist from allocating its sentinal object (for 
end()) eagerly to allocating it lazily.  This saves a lot of memory for JIT applications
that read a module but don't materialize most of the functions (e.g. 62K for 252.eon).

fe8e14a6c9 This adds a bunch of static functions that implement unsigned 
two's complement bignum arithmetic.  They could be used to
implement much of APInt, but the idea is they are enough to
implement APFloat as well, which the current APInt interface
is not suited for.

Patch by Neil Booth!

276222a5ae Change casts from old style to new style. This helps document the details 
better, gives the compiler a chance to validate the cast and reduces warnings
if the user turns on -Wold-style-cast option.

b1183c1ff3 This fixes resizing issues with BitVectors. It ensures that the BitWord type and type size is always used, and ensures completely correct clearing of unused high bits, and setting of bits when resizing. It should resolve PR1563.

42e4bdf257 When clearing a SmallPtrSet, if the set had a huge capacity, but the 
contents of the set were small, deallocate and shrink the set.  This
avoids having us to memset as much data, significantly speeding up
some pathological cases.  For example, this speeds up the verifier
from 0.3899s to 0.0763 (5.1x) on the testcase from PR1432 in a 
release build.
