645fc4edc2 if functiontype is going to have a pointer to a paramattr object, it better
be const.  The only way to get a pointer to these returns a const pointer.

b10308e440 Propagate changes from my local tree. This patch includes:
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.

c10305743c For PR1043:
This is the final patch for this PR. It implements some minor cleanup
in the use of IntegerType, to wit:
1. Type::getIntegerTypeMask -> IntegerType::getBitMask
2. Type::Int*Ty changed to IntegerType* from Type*
3. ConstantInt::getType() returns IntegerType* now, not Type*

This also fixes PR1120.

Patch by Sheng Zhou.

a54b7cbd45 For PR1064:
Implement the arbitrary bit-width integer feature. The feature allows
integers of any bitwidth (up to 64) to be defined instead of just 1, 8,
16, 32, and 64 bit integers.

This change does several things:
1. Introduces a new Derived Type, IntegerType, to represent the number of
   bits in an integer. The Type classes SubclassData field is used to
   store the number of bits. This allows 2^23 bits in an integer type.
2. Removes the five integer Type::TypeID values for the 1, 8, 16, 32 and
   64-bit integers. These are replaced with just IntegerType which is not
   a primitive any more.
3. Adjust the rest of LLVM to account for this change.

Note that while this incremental change lays the foundation for arbitrary
bit-width integers, LLVM has not yet been converted to actually deal with
them in any significant way. Most optimization passes, for example, will
still only deal with the byte-width integer types.  Future increments
will rectify this situation.

2c261789d3 Change the syntax for parameter attributes:
1. The @ sign is no longer necessary.
2. We now support "function attributes" as parameter attribute 0.
3. Instead of locating the return type attributes after the type of a
   function result, they are now located after the function header's
   closing paranthesis and before any alignment or section options.
4. The way has been prepared for a new "noreturn" function attribute but
   there is no support for recognizing it in the lexer nor doing anything
   with it if it does get set.
5. The FunctionType::getParamAttrsText method now has support for
   returning multiple attributes. This required a change in its interface.

I'm unhappy that this change leads to 6 new shift/reduce conflicts, but
in each case bison's decision to choose the shift is correct so there
shouldn't be any damage from these conflicts.
