Put the parameter attributes in their own ParamAttr name space. Adjust the
rest of llvm as a result.

Check at the end of the parse that there are no unresolved types and no
undefined values. Issue errors if there are. This gets rid of the need
for implementation or checkpoint by ensuring you can't finish a parse with
undefined things.

describes its function as check against unresolved types and definitions.
This is handy for forcing error messages in assembly test cases or otherwise
ensuring that everything is resolved at that point in the assembly.

Eliminate support for type planes in numbered values. This simplifies the
data structures involved in managing forward definitions, etc. Instead of
requiring maps from type to value, we can now just use a vector of values.
These changes also required rewrites of some support functions such as
InsertValue, getBBVal, and ResolveDefinitions. Some other cosmetic changes
were made as well.

Account for the sign bit when computing the number of bits required for
a negative integer literal constant.

Positive, negative, and hexadecimal integer constants will now return an
APInt for values having > 64 bits of precision.

tokens: ESAPINTVAL and EUAPINTVAL and adding an APInt* as a semantic value.
This allows us to extend the definition of an integer constant to allow
arbitrary precision integer constant values.

This patch replaces the SymbolTable class with ValueSymbolTable which does
not support types planes. This means that all symbol names in LLVM must now
be unique. The patch addresses the necessary changes to deal with this and
removes code no longer needed as a result. This completes the bulk of the
changes for this PR. Some cleanup patches will follow.

This feature is needed in order to support shifts of more than 255 bits
on large integer types. This changes the syntax for llvm assembly to
make shl, ashr and lshr instructions look like a binary operator:
shl i32 %X, 1
instead of
shl i32 %X, i8 1
Additionally, this should help a few passes perform additional optimizations.

1. New parameter attribute called 'inreg'. It has meaning "place this
parameter in registers, if possible". This is some generalization of
gcc's regparm(n) attribute. It's currently used only in X86-32 backend.
2. Completely rewritten CC handling/lowering code inside X86 backend.
Merged stdcall + c CCs and fastcall + fast CC.
3. Dropped CSRET CC. We cannot add struct return variant for each
target-specific CC (e.g. stdcall + csretcc and so on).
4. Instead of CSRET CC introduced 'sret' parameter attribute. Setting in
on first attribute has meaning 'This is hidden pointer to structure
return. Handle it gently'.
5. Fixed small bug in llvm-extract + add new feature to
FunctionExtraction pass, which relinks all internal-linkaged callees
from deleted function to external linkage. This will allow further
linking everything together.
NOTEs: 1. Documentation will be updated soon.
2. llvm-upgrade should be improved to translate csret => sret.
Before this, there will be some unexpected test fails.
