replaceAllUsesWith'ing any forward references, just use the forward
reference if it exists.
This introduces GetForwardRefForGlobal, which will eventually completely
replace the horrible DeclareNewGlobalValue function.

to substantially simplify the result. In particular, we no longer create
GlobalVariables and then immediately destroy them when they are duplciate
definitions.
The real point of this patch though is that it gets us closer to the
DeclareNewGlobalValue calls...

This gives us only a single call site for setValueNameMergingDuplicates.
The next stage is the start merging them together.

Since the stupid '%X = const int 4' thing is gone, we can now simplify
setValueNameMergingDuplicates a bit more.

for a basic block, use it when the block is defined instead of deleting it
and creating a new one. Also, only create at most ONE forward reference
for any block, instead of one for each forward reference.

forward reference blocks if they have been created (instead of creating a new
block, replaceAllUsesOfWith, then nuking the placeholder). This is not yet
implemented.

just to keep track of some per-object state! Gaah! Whoever wrote this stuff...
oh wait, that would be me. Never mind.

the funciton symbol table to check for conflicts instead of having to
keep a shadow named LocalSymtab. Totally eliminate LocalSymtab. Verified
that this did not cause a regression on the testcase for PR107.

1. Split setValueName into two separate functions, one that is only used
at function scope and doesn't have to deal with duplicates, and one
that can be used either at global or function scope but that does deal
with conflicts. Conflicts were only in there because of the crappy old
CFE and probably should be entirely eliminated.
2. Insert BasicBlock's into the parent functions when they are created
instead of when they are complete. This effects name lookup (for the
better), which will be exploited in the next patch.

"load (cast foo)". This allows us to compile C++ code like this:
class Bclass {
public: virtual int operator()() { return 666; }
};
class Dclass: public Bclass {
public: virtual int operator()() { return 667; }
} ;
int main(int argc, char** argv) {
Dclass x;
return x();
}
Into this:
int %main(int %argc, sbyte** %argv) {
entry:
call void %__main( )
ret int 667
}
Instead of this:
int %main(int %argc, sbyte** %argv) {
entry:
%x = alloca "struct.std::bad_typeid" ; <"struct.std::bad_typeid"*> [#uses=3]
call void %__main( )
%tmp.1.i.i = getelementptr "struct.std::bad_typeid"* %x, uint 0, uint 0, uint 0 ; <int (...)***> [#uses=1]
store int (...)** getelementptr ([3 x int (...)*]* %vtable for Bclass, int 0, long 2), int (...)*** %tmp.1.i.i
%tmp.3.i = getelementptr "struct.std::bad_typeid"* %x, int 0, uint 0, uint 0 ; <int (...)***> [#uses=1]
store int (...)** getelementptr ([3 x int (...)*]* %vtable for Dclass, int 0, long 2), int (...)*** %tmp.3.i
%tmp.5 = load int ("struct.std::bad_typeid"*)** cast (int (...)** getelementptr ([3 x int (...)*]* %vtable for Dclass, int 0, long 2) to int
("struct.std::bad_typeid"*)**) ; <int ("struct.std::bad_typeid"*)*> [#uses=1]
%tmp.6 = call int %tmp.5( "struct.std::bad_typeid"* %x ) ; <int> [#uses=1]
ret int %tmp.6
ret int 0
}
In order words, we now resolve the virtual function call.

- Remove tabs
- Standardize use of space around ( and ).
- Consolidate the ConstantPlaceHolder class
- Rename two methods to be more meaningful (ParseType, ParseTypes)
- Correct indentation of blocks
- Add documentation
- Convert input dependent asserts to error(...) so it throws instead.
Provide placeholder implementations of read_float and read_double that
still read in platform-specific endianess. When I figure out how to do
this without knowing the endianess of the platform, it will get implemented
correctly.

- Add read_float and read_double in preparation for a correct
implementation of bytecode floating point support.

lli -load libparisc.so -march=parisc foo.bc
