Chris Lattner b35583df52 add a new driver-level -ferror-limit=412 option, which causes clang to stop 
emitting diagnostics after it has produced that many errors.  Give this a
default value of 20 which produces plenty of errors for people to fix before
recompiling but not so many that their entire console scrolls away when the
compiler gets confused.  The experience looks like this:

$ clang foo.c
<tons of crap>
foo.c:102:3: error: unknown type name 'somethingbad'
  somethingbad x;
  ^
fatal error: too many errors emitted, stopping now
36 warnings and 20 errors generated.

Douglas Gregor 0086a5a3bb Introduce the notion of "Relocatable" precompiled headers, which are built 
with a particular system root directory and can be used with a different
system root directory when the headers it depends on have been installed.
Relocatable precompiled headers rewrite the file names of the headers used
when generating the PCH file into the corresponding file names of the 
headers available when using the PCH file.

Addresses <rdar://problem/7001604>.
