6ad5fde5d0 Have DenseMap auto-shrink itself on clear(). This improves the time to optimize
403.gcc from 15.2s to 14.3s.

c5c7f755c8 Evidently my earlier fix did not go far enough. When resizing a zero-sized
BitVector, make sure to set or clear ALL of the bits.

df799afbec Fix some sporadic segfaults that are triggered when SmallVector's heap
storage lands near the end of the available address space. In the expression
Begin+N > Capacity, the Begin+N was overflowing. Fix this by replacing it
by with an expression that doesn't involve computation of an address
beyond the end of allocated memory.

19dc32a2d4 Add some things needed by the llvm-gcc version supporting bit accurate integer
types:
1. Functions to compute div/rem at the same time.
2. Further assurance that an APInt with 0 bitwidth cannot be constructed.
3. Left and right rotate operations.
4. An exactLogBase2 function which requires an exact power of two or it
   returns -1.

47e756c11e Commit an patch from Gabor Greif in Mar 2005. This eliminates the tail
pointer from ilist, storing it in the prev pointer of the first node in the
list instead.

This shrinks ilist from 8 to 4 bytes, BasicBlock from 40->36 bytes, Function
from 76->68 bytes, Module from 52->44 bytes.

db8918a98f Add a helper class (APSInt) which can represent an APInt along with sign

it.  This shouldn't be used generally in LLVM for mid-level optimizer stuff.

f6bef488ee Compute getLowBitsSet correctly. Using the complement of a 64-bit value
and shifting down without regard for the bitwidth of the APInt can lead
to incorrect initialization values. Instead, check for the word size case
(to avoid undef results from shift) and then do (1 << loBitsSet) - 1

a1689ea60e Actually, for getHighBitsSet and getLowBitsSet, don't make a 0 bit size
illegal. Instead do the 0 valued construction for the user. This is because
the caller may not know (or care to check) that the number of bits set is
zero.

758d1bc919 Make it illegal to set 0 bits in getHighBitsSet and getLowBitsSet. For that
they should have used the uint64_t constructor. This avoids causing
undefined results via shifts by the word size when the bit width is an
exact multiple of the word size.

5b7e659e22 In the getBitsSet function, don't optimize for a common case that is
already covered by getLowBitsSet (i.e. when loBits==0). Consequently, remove
the default value for loBits and reorder the arguments to the more natural
loBits, hiBits order. This makes it more clear that this function is for bit
groups in the middle of the bit width and not towards one end or the other.
