b065b06c12 Revamp the "ConstantStruct::get" methods. Previously, these were scattered
all over the place in different styles and variants.  Standardize on two
preferred entrypoints: one that takes a StructType and ArrayRef, and one that
takes StructType and varargs.

In cases where there isn't a struct type convenient, we now add a
ConstantStruct::getAnon method (whose name will make more sense after a few
more patches land).  

It would be "really really nice" if the ConstantStruct::get and 
ConstantVector::get methods didn't make temporary std::vectors.

0cd0d88160 eliminate the Type::getDescription() method, using "<<" instead. This
removes some gunk from LLVMContext.

916a94b870 Add an option that allows one to "decode" the LSDA.
The LSDA is a bit difficult for the non-initiated to read. Even with comments,
it's not always clear what's going on. This wraps the ASM streamer in a class
that retains the LSDA and then emits a human-readable description of what's
going on in it.

So instead of having to make sense of:

Lexception1:
        .byte   255
        .byte   155
        .byte   168
        .space  1
        .byte   3
        .byte   26
Lset0 = Ltmp7-Leh_func_begin1
      .long     Lset0
Lset1 = Ltmp812-Ltmp7
      .long     Lset1
Lset2 = Ltmp913-Leh_func_begin1
      .long     Lset2
      .byte     3
Lset3 = Ltmp812-Leh_func_begin1
      .long     Lset3
Lset4 = Leh_func_end1-Ltmp812
      .long     Lset4
      .long     0
      .byte     0
      .byte     1
      .byte     0
      .byte     2
      .byte     125
      .long     __ZTIi@GOTPCREL+4
      .long     __ZTIPKc@GOTPCREL+4

you can read this instead:

## Exception Handling Table: Lexception1
##  @LPStart Encoding: omit
##    @TType Encoding: indirect pcrel sdata4
##        @TType Base: 40 bytes
## @CallSite Encoding: udata4
## @Action Table Size: 26 bytes

## Action 1:
##   A throw between Ltmp7 and Ltmp812 jumps to Ltmp913 on an exception.
##     For type(s):  __ZTIi@GOTPCREL+4 __ZTIPKc@GOTPCREL+4
## Action 2:
##   A throw between Ltmp812 and Leh_func_end1 does not have a landing pad.

7c863eb8cc Bugpoint support for miscompilations that result in a crash.
This change allows bugpoint to pinpoint the "opt" pass and bitcode
segment responsible for a crash caused by miscompilation. At least it
works well for me now, without having to create any custom execution
wrappers.

debd7e4e8b Simplify the handling of pcrel relocations on ELF. Now we do the right thing
for all symbol differences and can drop the old EmitPCRelSymbolValue
method.

This also make getExprForFDESymbol on ELF equal to the one on MachO, and it
can be made non-virtual.

f8c1c8465f MCJIT lazy relocation resolution and symbol address re-assignment.
Add handling for tracking the relocations on symbols and resolving them.
Keep track of the relocations even after they are resolved so that if
the RuntimeDyld client moves the object, it can update the address and any
relocations to that object will be updated.

For our trival object file load/run test harness (llvm-rtdyld), this enables
relocations between functions located in the same object module. It should
be trivially extendable to load multiple objects with mutual references.

As a simple example, the following now works (running on x86_64 Darwin 10.6):


$ cat t.c
int bar() {
  return 65;
}

int main() {
  return bar();
}
