eee1022086 Switch the bitcode reader interface to take a MemoryBuffer instead of knowing 
anything about disk I/O itself.  This greatly simplifies its interface -
eliminating the need for the ReaderWrappers.cpp file.

This adds a new option to llvm-dis (-bitcode) which instructs it to read
the input file as bitcode.  Until/unless the bytecode reader is taught to
read from MemoryBuffer, there is no way to handle stdin reading without it.

I don't plan to switch the bytecode reader over, I'd rather delete it :),
so the option will stay around temporarily.

e884f9cb2a Fix for PR1306. 
- A register def / use now implicitly affects sub-register liveness but does
not affect liveness information of super-registers.

read/mod/write of a smaller register.

48352d7a71 Copy coalescing change to prevent a physical register from being pin to a 
long live interval that has low usage density.
1. Change order of coalescing to join physical registers with virtual
   registers first before virtual register intervals become too long.
2. Check size and usage density to determine if it's worthwhile to join.
3. If joining is aborted, assign virtual register live interval allocation
   preference field to the physical register.
4. Register allocator should try to allocate to the preferred register
   first (if available) to create identify moves that can be eliminated.

cc56e116fe The (negative) offset from a SymbolTableListTraits-using ilist to its container 
object is always constant.  As such, evaluate it at compile time instead of storing
it as an ivar in SymbolTableListTraits.  This shrinks every SymbolTableListTraits
ilist by a word, shrinking BasicBlock from 44->40 bytes, Function from 96->88 bytes,
and Module from 60->52 bytes.

read a module header from 565680b to 561024, a little over 4K.

at static init time, changing it to build local data structures when ParseCommandLineOptions

the number of malloc'd bytes from 4864 to 3360 on entry to main.  Most of that
memory is now allocated by non-commandline related stuff.

4984ab6c01 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

16d08887ef 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.

d24dc1f9a6 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.

fb188ea881 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.
