Implement the new environment pointer for ExecuteAndWait

llvm-svn: 18928

Implement three new functions to allow setting access/permission bits on
the file referenced by a path. The makeReadable and makeExecutable methods
replace the FileUtilities MakeFileReadable and MakeFileExecutable
functions. The makeWritable function is new and provided for consistency
since Path has a writable() method.

* Correct the std::string constructor to take a const reference.

llvm-svn: 18877

* Remove IsLibrary and GetLibraryPath, replaced by FindLibrary in ../Path.cpp \
* Implement GetSystemLibraryPaths and GetBytecodeLibraryPaths, instead of the \
  GetSystemLibraryPath1 and GetSystemLibraryPath2 methods

library (shared library/shared object) whose symbols can be looked up
dynamically. Used for plug-ins.

* Don't use variable length arrays (replaced with alloca)

* get rid of (void) construct in function declarations
* make toString a const member
* add a default implementation of toString for Win32

llvm-svn: 17873

* Clean up the StatusInfo constructor to construct all members and give
  them reasonable values.
* Get rid of the Vector typedef and make the interface to
  getDirectoryContent use a std::set instead of a std::vector so the dir
  content is sorted.
* Make the getStatusInfo method const and not return a useless boolean.

class needs to implement an alternate mechanism based on malloc'd memory
and file reading/writing for platforms without virtual memory.
