to eliminate some casting.

331dbca73db75bbb87fcd81e2b8a68c9195de8b5 15-Jul-2011 Frits van Bommel <fvbommel@gmail.com> In Twine::str(), if the Twine stores only a std::string, just return a direct copy of that instead of first copying to a SmallString and converting that to a std::string. Also fix some indentation.

ea03e10facd07f0b239dcc3a5e31346686acae3c 05-May-2010 Chris Lattner <sabre@nondot.org> Implement rdar://7415680 - Twine integer support lacks greatness

Microoptimize Twine's with unsigned and int to not pin their value to
the stack. This saves stack space in common cases and allows mem2reg
in the caller. A simple example is:

void foo(const Twine &);
void bar(int x) {
foo("xyz: " + Twine(x));
}

Before:

__Z3bari:
subq $40, %rsp
movl %edi, 36(%rsp)
leaq L_.str3(%rip), %rax
leaq 36(%rsp), %rcx
leaq 8(%rsp), %rdi
movq %rax, 8(%rsp)
movq %rcx, 16(%rsp)
movb $3, 24(%rsp)
movb $7, 25(%rsp)
callq __Z3fooRKN4llvm5TwineE
addq $40, %rsp
ret

After:

__Z3bari:
subq $24, %rsp
leaq L_.str3(%rip), %rax
movq %rax, (%rsp)
movslq %edi, %rax
movq %rax, 8(%rsp)
movb $3, 16(%rsp)
movb $7, 17(%rsp)
leaq (%rsp), %rdi
callq __Z3fooRKN4llvm5TwineE
addq $24, %rsp
ret

It saves 16 bytes of stack and one instruction in this case.

twine can be represented as a single StringRef. Use the new methode to simplify
some twine users.

763457e70bc9c5c2def89d24a133808b8a971f9f 29-Jul-2009 Daniel Dunbar <daniel@zuster.org> Twines: Support numeric conversion directly (uitostr, etc).
- Provides static constructors for doing number to string conversions without
using temporaries.

- There are several ways to do this, I think given the Twine constraints this
is the simplest one.

- One FIXME for fast number -> hex conversion.

- Added another comment on one last major bit of perf work Twines need, which
is to make raw_svector_ostream more efficient.
