22f9dd4591 MC asm parser: allow ?'s in symbol names, and handle @'s in names in MS asm
This is another (final?) stab at making us able to parse our own asm output
on Windows.

Symbols on Windows often contain @'s and ?'s in their names. Our asm parser
didn't like this. ?'s were not allowed, and @'s were intepreted as trying to
reference PLT/GOT/etc.

We can't just add quotes around the bad names, since e.g. for MinGW, we use gas
to assemble, and it doesn't like quotes in some places (notably in .def
directives).

This commit makes us allow ?'s in symbol names, and @'s in symbol names for MS
assembly.

6cd04fdaae [PATCH] Fix PR17168 (DAG scheduler inserts DBG_VALUE before PHI with fast-isel)
PR17168 describes a test case that fails when compiling for debug with
fast-isel.  Investigation showed that the test was failing because a DBG_VALUE
machine instruction was placed prior to a PHI.

For this problem to occur requires the following:
 * Compile for debug
 * Compile with fast-isel
 * In a block B, fast-isel must partially succeed before punting to DAG-isel
 * B must start with a PHI
 * The first unhandled node in the DAG must not generate a machine instruction
 * A debug value with an order less than that of that first node exists

When all of these circumstances apply, the existing test that an instruction
was not inserted won't fire.  Currently it tests whether the block is empty,
or whether the last instruction generated is a phi.  When fast-isel has
partially succeeded, the last instruction generated will not be a phi.
Instead, we need to check whether the current insert position is immediately
following a phi.  This patch adds that check, and adds the test case from the
PR as a regression test.

7014d274e4 17309 ARM backend incorrectly lowers COPY_STRUCT_BYVAL_I32 for thumb1 targets
This commit implements the correct lowering of the
COPY_STRUCT_BYVAL_I32 pseudo-instruction for thumb1 targets.
Previously, the lowering of COPY_STRUCT_BYVAL_I32 generated the
post-increment forms of ldr/ldrh/ldrb instructions. Thumb1 does not
have the post-increment form of these instructions so the generated
assembly contained invalid instructions.

Passing the generated assembly to gcc caused it to complain with an
error like this:

  Error: cannot honor width suffix -- `ldrb r3,[r0],#1'

and the integrated assembler would generate an object file with an
invalid instruction encoding.

This commit contains a small test case that demonstrates the problem
with thumb1 targets as well as an expanded test case that more
throughly tests the lowering of byval struct passing for arm,
thumb1, and thumb2 targets.

6483751a36 Refactor lowering for COPY_STRUCT_BYVAL_I32
This commit refactors the lowering of the COPY_STRUCT_BYVAL_I32
pseudo-instruction in the ARM backend. We introduce a new helper
class that encapsulates all of the operations needed during the
lowering. The operations are implemented for each subtarget in
different subclasses. Currently only arm and thumb2 subtargets are
supported.

This refactoring was done to easily implement support for thumb1
subtargets. This initial patch does not add support for thumb1, but
is only a refactoring. A follow on patch will implement the support
for thumb1 subtargets.

No intended functionality change.
