14b42c0040 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.

373d2bccea 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.

4f14887126 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.

38002bb037 For PR950: 
Remove all grammar conflicts from assembly parsing.  This change involves:
1. Making the "type" keyword not a primitive type (removes several
   reduce/reduce conflicts)
2. Being more specific about which linkage types are allowed for functions
   and global variables. In particular "appending" can no longer be
   specified for a function. A differentiation was made between the various
   internal and external linkage types.
3. Introduced the "define" keyword which is now required when defining a
   function. This disambiguates several cases where a named function return
   type could get confused with the definition of a new type. Using the
   keyword eliminates all shift/reduce conflicts and the remaining
   reduce/reduce conflicts.

These changes are necessary to implement the function parameter attributes
that will be introduced soon. Adding the function parameter attributes in
the presence of the shift/reduce and reduce/reduce conflicts led to severe
ambiguities that caused the parser to report syntax errors that needed to
be resolved. This patch resolves them.

9ac4a6b7d0 Remove the last use of getUnsignedVersion and getSignedVersion from VMCore. 
ConstantInt doesn't care about the sign of the type it represents. It only
cares about the bitwidth so there is no need to make the sign of the type
match the SExt or ZExt constant expression.

ce05d51e82 Adjust the interface to ConstantArray::get. The previous 
implementation always added a null byte to the end of the string. It turns
out that this is not always wanted. By adding a length parameter we preserve
this behavior when length==0 (default value) but also allow other lengths
(not null terminated) to be created.
