550242f7ec Use context-sensitive alias analysis to avoid pessimization in clients of
AliasSetTracker (dse and licm).  This implements
DeadStoreElimination/context-sensitive.llx

313fb44da9 New testcase for list slicing

8dcbaf2f98 Add initial support for list slices. This currently allows you to do stuff
like this:

def B {
  list<int> X = [10, 20, 30, 4, 1, 1231, 20] [2-4,2,2,0-6];
}

... which isn't particularly useful, but more is to come.

bf4651aa66 A utility to run an arbitrary program on each of the LLVM source files.
This is like llvmgrep but instead of running grep, it runs the command
given by the first argument. For example, to find the top ten files with
the most lines in llvm, you could:

utils/llvmdo wc -l | sort -nb | tail

Or, to find any source files with the wrong permissions, you could:

utils/llvmdo ls -l | grep -v rw-r--r--

Hopefully, you get the idea.

a979e8a08a ADDI can take several forms, including:
addi r1, r2, 0
  addi r1, <frame index #n>, 0

so we must check for the second parameter being a register for this instruction
to be considered a reg-to-reg copy.

e643adb9e5 Fix a serious bug in the double constant reader. In particular, because
(At[3] << 24) is an int type and it is being coerced to uint64_t, it was
getting sign extended, causing us to get FFFFFFFFxxxxxxxx constants all of
the time.

1649c7d308 Temporarily disable this code, as it is emitting LLVM_NAN("nan") which results in a call to the
glibc 'nan' function because the initializer is not a string.  This breaks when used in a global
initializer.  Try compiling this testcase for example:

%X = global float <some nan value>

- encode/decode target triple and dependent libraries
bug 401:
- fix encoding/decoding of FP values to be little-endian only
bug 402:
- initial (compatible) cut at 24-bit types instead of 32-bit
- reduce size of block headers by 50%
Other:
- cleanup Writer by consolidating to one compilation unit, rem. other files
- use a std::vector instead of std::deque so the buffer can be allocated
  in multiples of 64KByte chunks rather than in multiples of some smaller
  (default) number.
