00f50519b6 Add new configure option, --disable-timestamps, intended to turn off anything which would mess up binary/object comparisons. Currently: 
- Disables 'Built on ...' in 'foo --version'.
 - Disables timestamps from being embedded into .dir files.

ca05b607b7 Refer to -help instead of --help since this is what tools themselves say. 
Also, have tools output -help-hidden rather than refer to --help-hidden,
for consistency, and likewise adjust documentation.  This doesn't change
every mention of --help, only those which seemed clearly safe.

d561db80e6 Move the handling of CommaSeparated options into ProvideOption. 
Makes '--comma-separated val1,val2' mean the same thing as
'--comma-separated=val1,val2' (that is, 'val1' and 'val2' are not lumped
together as 'val1,val2'). Also declutters the main loop a bit.

f3f063a58e Revert CPU detection code to return "generic" instead of an empty string in case 
of failure. The x86 target didn't like empty cpu names and broke x86 tests on
non-x86 buildbots.

bde5513d27 Bugfix for the CommaSeparated option. The original code was adding the whole 
string at the end of the list, instead of the last comma-separated string.

2ca8a35c0f Roll back r82348, which introduced an infinite loop in ParseCStringVector() that 
a trivial unittest would have caught.  This revision also adds the trivial
unittest.

3a20fca97c don't use count + insert, just do insert + failure. Also, instead of deleting from 
the middle of a vector, swap the last element in and pop_back.  Also saves 330 bytes :)

6a6a75896d Several changes together in a murky mess: 
1. Change some "\n" -> '\n'.
2. eliminte some std::string's by using raw_ostream::indent.
3. move a bunch of code out of the main arg parser routine into
   a new static HandlePrefixedOrGroupedOption function.
4. Greatly simplify the implementation of getOptionPred, and make
   it avoid splitting prefix options at = when that doesn't match
   a non-prefix option.

This requires StringRef'izing ProvideOption which I also did.

85478e8cd1 convert a bunch more stuff to use StringRef. The ArgName arguments are now 
stringref because they may not be nul terminated.  For options like -Lfoo
this now avoids a O(n)  temporary std::strings where N is the length of 
the string after -L.

a massive number of temporary strings created when parsing a command line.
More still left to eliminate.

- Eliminate unnecessary std::string copies

f955a6ef49 llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable. 
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

ae8a3ff177 assert(0) -> LLVM_UNREACHABLE. 
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.
