473f8a6f88 Driver: Reject -fasm-blocks except on X86 (where we just ignore it, since 
passing it is very prevalent in some circles).

2b4de14b1d Driver/IA: Accept and ignore -force_cpusubtype_ALL, as in 'clang -c 
-Wa,-force_cpusubtype_ALL t.c'.
 - Tweaks -Wa, and -Xassembler handling to only accept an explicit short list of
   arguments and give an obvious unsupported error on others.

4e0f15a4a2 Eliminate -fdiagnostics-binary and all of the infrastructure for 
emitting diagnostics in a binary form to be consumed by libclang,
since libclang no longer does any of its work out-of-process, making
this code dead. Besides, this stuff never worked at 100% anyway.

right place to do it.

91bbb5547d Introduce -flimit-debug-info. 
In this experimental mode try avoiding debug info emission for classes as much as possible. The goal is to reduce size of produced debuginfo without reducing quality of debug info in general. This is a work in progress.

dd84ef1e62 Add a -ftrapv-handler= option which allows a handler to invoke instead of simply aborting when a signed operation overflows. This mirrors the (GCC-incompatible) behaviour from clang 1.0 and 1.1 when -ftrapv was specified, but allows the handler to be defined for each compilation unit.

2cc3f17a26 Driver: Add magic handling for "reserved library names", starting with 
-lstdc++. This is the best gross solution for a gross problem.

This issue is that historically, GCC has add -L options to its internally
library directories. This has allowed users and platforms to end up depending on
the layout of GCC's internal library directories.

We want to correct this mistake by eliminating that -L, but this means that
existing libraries which are in the GCC lib dir won't be found. We are going to
handle this by treating those -l names as "reserved", and requiring toolchains
to know how to add the right full path to the reserved library.

The immediately side effect of this is that users trying to use -L to find their
own -lstdc++ will need to start using -nostdlib (which is a good idea
anyway). Another side effect is that -stdlib=libc++ -lstdc++ will now do the
"right" thing, for curious definitions of right.

fe6c97b443 Driver/Clang: Forward -Wa, and -Xassembler to clang -cc1 when using the

someone tries to use this mechanism to send an argument to the assembler.

82eb4ce476 Driver: Move Clang "triple" computation routines to method on the 
ToolChain. This fixes a potenial bad cast when running Clang on PPC code, since
the tool chain in effect is not a subclass of the Darwin one, but we were
treating it like it was.
 - This introduces some gross code duplication, but the right fix for it is to
   just move the Driver to start depending on the targets in libBasic, so I am
   not planning on fixing it immediately.

589a494352 Pass some things to the linker that gcc passes. -r is the only one of these that I'm sure about, but the others seem to be listed on FreeBSD by gcc -dumpspecs, so I hope they're right. Apparently -r is also not passed on GNU/Linux (and should be), but I can't see where the toolchain definition for this platform live.
