81244298ea Properly quote the quotes :) during cmdline construction on Windows. 
Otherwise, e.g. in the invocation like clang -DFOO=\"bar\" FOO macro
got the bar value, not "bar".

b7ccf75de5 Fix a false-positive memory leak in code using RemoveFileOnSignal(). Because 
libstdc++'s std::string class points to the interior of an allocation, valgrind
reports strings still alive at program termination as possible leaks.  I didn't
use a ManagedStatic for this because System can't depend on Support.

6220754525 Make clang bootstrap happier on OSX 10.5 by reducing the number of headers 
included when using global symbols to ask the linker for the addresses of
various functions.  One of the symbols was actually getting declared by a
header included in DynamicLibrary.cpp, which conflicted with the "extern void*"
declaration in SearchForAddressOfSpecialSymbol().

0f706ab789 Move the extern symbol declarations outside of 
DynamicLibrary::SearchForAddressOfSymbol and force them to have "C"
linkage. 

Interestingly, GCC treats the block-scoped "extern" declarations we
previously had as if they were extern "C" declarations (or, at least,
were in the global namespace), so that GCC bug papered over this LLVM
bug. Clang and EDG get the linkage correct; this new variant seems to
work for both GCC and Clang.

another solution.

ec080467f5 Fix llvm-extract's "writing bitcode to a terminal" warning, which wasn't 
working. To support this, add an is_displayed() function to raw_ostream,
and generalize Process::StandardOutIsDisplayed and friends in order to
support it.

Also, call RemoveFileOnSignal before creating a file instead of after, so
that the file isn't left behind if the program is interrupted between when
the file is created and RemoveFileOnSignal is called.

While here, add a -S to llvm-extract and port it to IRReader so that it
supports assembly input.

74382b7c69 Prune #includes from llvm/Linker.h and llvm/System/Path.h, 
forcing them down into various .cpp files.

This change also:
1. Renames TimeValue::toString() and Path::toString() to ::str()
   for similarity with the STL.
2. Removes all stream insertion support for sys::Path, forcing
   clients to call .str().
3. Removes a use of Config/alloca.h from bugpoint, using smallvector
   instead.
4. Weans llvm-db off <iostream>

sys::Path really needs to be gutted, but I don't have the desire to
do it at this point.

6db0a8b4fd When exec() fails, return 127 instead of errno; the parent process has no way to 
distinguish that the result is errno, so it can't use it to provide more
information about the error (it also exposes the numeric value of errno).

81ce3ed08c Make the JIT code emitter properly retry and ask for more memory when it runs 
out of memory, and also make the default memory manager allocate more memory
when it runs out.

Also, switch function stubs and global data over to using the BumpPtrAllocator.

This makes it so the JIT no longer mmaps (or the equivalent on Windows) 16 MB
of memory, and instead allocates in 512K slabs.  I suspect this size could go
lower, especially on embedded platforms, now that more slabs can be allocated.
