5927323d9c Add a std::string Wrapper for TableGen 
Create a std::string wrapper for use as a DenseMap key.  DenseMap is
not safe in generate with strings, so this wrapper indicates that only
strings guaranteed not to have certain values should be used in the
DenseMap.

7ec2a31f14 Turns out llvm-gcc still uses SplitString with a vector. Add it back until I 
have a fix.

cdbc36f961 Reimplement getToken and SplitString as "StringRef helper functions" 
- getToken is modeled after StringRef::split but it can split on multiple
  separator chars and skips leading seperators.
- SplitString is a StringRef::split variant for more than 2 elements with the
  same behaviour as getToken.

46166d50a8 split out the functionality of utohexstr into a new utohex_buffer 
helper.  This allows us to convert numbers to hex without necessarily
needing to make a std::string to hold the result.

3ad0263173 Make tblgen a little smarter about constants smaller than i32. Currently, 
tblgen will complain if a sign-extended constant does not fit into a
data type smaller than i32, e.g., i16. This causes a problem when certain
hex constants are used, such as 0xff for byte masks or immediate xor
values.

tblgen will try the sign-extended value first and, if the sign extended
value would overflow, it tries to see if the unsigned value will fit.
Consequently, a software developer can now safely incant:

	(XORHIr16 R16C:$rA, 0xffff)

which is somewhat clearer and more informative than incanting:

	(XORHIr16 R16C:$rA, (i16 -1))

even if the two are bitwise equivalent.

Tblgen also outputs the 64-bit unsigned constant in the generated ISel code
when getTargetConstant() is invoked.

2429ec5fdf Fix utostr once and for all, by making there only be one function named 
utostr.  To keep the efficiency in the 32-bit case, make it check to see if
the value is 32-bits and if so switch over to the faster 32-bit case.

574d4e6992 For PR786: 
Minor tweaks in public headers and a few .cpp files so that LLVM can build
successfully with -pedantic and projects using LLVM with -pedantic don't
get warnings from LLVM. There's still more -pedantic warnings to fix.

61bed2fe76 Do not let 'ftostr' return a string that starts with spaces. This allows 
the AsmWriter to emit FP constants like 1.0 in normal exponential notation
instead of hex notation.
