c984df8602 Add TargetInfo libraries for all targets.
- Intended to match current TargetMachine implementations.

 - No facilities for linking these in yet.

bb06129140 Add new TargetRegistry.
Targets implement a single global Target structure which will live in a new
<Target>/TargetInfo library; this will be present in any image which the target
is usable in.
 - Optional target specific classes can then be registered and attached to the
   Target description.

 - Registration for normal Targets will be done via the initialization functions
   instead of using static constructors.

 - This allows clients to use a single interface to obtain target data, without
   requiring the code generator be linked in. It also provides a natural
   extension point for adding new optional target data (assembler parser,
   disassembler, etc.).

 - This also provides a new entry point for obtaining a target for a particular
   triple (without a module).

 - Not yet used, however this should eventually replace the TargetMachineRegistry.

stub generation to make sure I don't break anything.

but it's just an assembler temporary, so the name doesn't matter.

b8158acc23 Reapply my previous asmprinter changes now with more testing and two
additional bug fixes:

1. The bug that everyone hit was a problem in the asmprinter where it
   would remove $stub but keep the L prefix on a name when emitting the
   indirect symbol.  This is easy to fix by keeping the name of the stub
   and the name of the symbol in a StringMap instead of just keeping a
   StringSet and trying to reconstruct it late.

2. There was a problem printing the personality function.  The current
   logic to print out the personality function from the DWARF information
   is a bit of a cesspool right now that duplicates a bunch of other 
   logic in the asm printer.  The short version of it is that it depends
   on emitting both the L and _ prefix for symbols (at least on darwin)
   and until I can untangle it, it is best to switch the mangler back to
   emitting both prefixes.

In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

03e9dd9ffa Change the X86 asmprinter to use the mangler to apply suffixes like "$non_lazy_ptr"
to symbols instead of doing it with "printSuffixedName".  This gets us to the point
where there is a real separation between computing a symbol name and printing it,
something I need for MC printer stuff.

This patch also fixes a corner case bug where unnamed private globals wouldn't get
the private label prefix.

Next up, rename all uses of getValueName -> getMangledName for better greppability,
and then tackle the ppc/arm backends to eliminate "printSuffixedName".

1cda87c3a0 Change the internal interface to makeNameProper to take a bool that
indicates whether the label is private or not, instead of taking
prefix stuff.  One effect of this is that symbols will be generated
with *just* the private prefix, instead of both the private prefix
*and* the user-label-prefix, but this doesn't matter as long as it
is consistent.  For example we'll now get "Lfoo" instead of "L_foo".
These are just assembler temporary labels anyway, so they never even
make it into the .o file.

a342026504 Introduce a new LoopInfo utility function makeLoopInvariant, which
works similar to isLoopInvariant, except that it will do trivial
hoisting to try to make the value loop invariant if it isn't already.
This makes it easier for transformation passes to clear trivial
instructions out of the way (the regular LICM pass doesn't run
until relatively late). This is code factored out of LoopSimplify
and other places.

59ecdfbee3 rename Memo/Count to AnonGlobalIDs/NextAnonGlobalID to be more
descriptive.  Thange them to keep track of the ID of a global that is
assigned, not the first mangled name returned for it.  Without doing this,
we are required to always use the same suffix for a global that gets 
mangled.  This means that we can mangle the same global once with $stub
and another time with $non_lazy_ptr or whatever.

d4f53b373e Two changes:
1) unique globals with the existing "Count" local in Mangler, not with
atomic nonsense.  Using atomics will give us nondeterminstic output

2) Do not mangle an unknown global name with a type suffix.  We don't
   need this anymore now that llvm ir doesn't have type planes.

65a7a6f7a3 fix x86-64 static codegen to materialize the address of a global with movl instead
of lea.  It is better for code size (and presumably efficiency) to use:

  movl $foo, %eax

rather than:

  leal foo, eax

Both give a nice zero extending "move immediate" instruction, the former is just
smaller.  Note that global addresses should be handled different by the x86
backend, but I chose to follow the style already in place and add more fixme's.

4f06649497 Fix PR4533, which is about buggy codegen in x86-64 -static mode.
Basically, using:
  lea symbol(%rip), %rax

is not valid in -static mode, because the current RIP may not be
within 32-bits of "symbol" when an app is built partially pic and
partially static.  The fix for this is to compile it to:

  lea symbol, %rax

It would be better to codegen this as:

  movq $symbol, %rax

but that will come next.


The hard part of fixing this bug was fixing abi-isel, which was actively
testing for the wrong behavior.  Also, the RUN lines are completely impossible
to understand what they are testing.  To help with this, convert the -static 
x86-64 codegen tests to use filecheck.  This is much more stable and makes it
more clear what the codegen is expected to be.

c25e7581b9 assert(0) -> LLVM_UNREACHABLE.

line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

646ca92bfc Fix handling of max and full set.
A full set is a constant range that represents any number. If you take the
umax of that and [5, 10) you end up with [5, INT_MAX] because the values less
than 5 would be umax's against a value which is at least 5.

446c428bf3 Major changes to Thumb (not Thumb2). Many 16-bit instructions either modifies CPSR when they are outside the IT blocks, or they can predicated when in Thumb2. Move the implicit def of CPSR to an optional def which defaults CPSR. This allows the 's' bit to be toggled dynamically.
A side-effect of this change is asm printer is now using unified assembly. There are some minor clean ups and fixes as well.

892837abf3 We don't need separate thumb1 instructions tADDSi3 etc. for addc and subc. The "normal" version always modify condition register CPSR so we should just use def : pat to match to the same instructions.

d15f45f53e If -fomit-frame-pointer is used, we still need to record when the %esp register
is modified. Otherwise, the unwinder will get confused. The old code (before I
started my hacking) did this. It dropped on the floor, because I wasn't aware of
this requirement.

On the plus side, if we use "alloca" in a function, we create frame pointers
even with -fomit-frame-pointer is enabled!

This is a Good Thing(tm)!!!

what ConstantRange does for unsigned integers. Factor out a
common base class for common functionality.

Add some new functions for performing arithmetic on constant
ranges. Some of these are currently just stubbed out with
conservative implementations.

Add unittests for ConstantRange and ConstantSignedRange.

DAGTypeLegalizer::PromoteIntRes_EXTRACT_VECTOR_ELT take advantage of 
this new flexibility to simplify the code and make it deal with unusual 
vectors (like <4 x i1>) correctly.  Fixes PR3037.

-t is already used by gcc in the meaning 'ld -t' (trace). The Base plugin may
 want to emulate this behaviour.
