Fix crash with two typos in the arguments of a function

The problem is that the arguments are of TheCall are reset later
to the ones in Args, making TypoExpr put back. Some TypoExpr that have
already  been diagnosed and will assert later in Sema::getTypoExprState

[ARM] Don't try and custom lower a vNi64 SETCC.

It won't go well. We've already marked 64-bit SETCCs as non-Custom, but it's
just possible that a SETCC has a legal result type but an illegal operand
type. If this happens, bail out before we create unselectable nodes.

Fixes PR24292. I tried to create a testcase but in 99% of cases we can't
trigger this - not surprising that this bug has been latent since 2009.

[PowerPC] Fix value type on XVCMPEQDP for v2f64 comparisons

XVCMPEQDP is used for VSX v2f64 equality comparisons, but the value type needs
to be v2i64 (as that's the corresponding SETCC type).

Fixes PR24225.

[PowerPC] Fix the int2fp(fp2int(x)) DAGCombine to ignore ppc_fp128

This DAGCombine was creating custom SDAG nodes with an illegal ppc_fp128
operand type because it was triggering on f64/f32 int2fp(fp2int(ppc_fp128 x)),
but shouldn't (it should only apply to f32/f64 types). The result was a crash.

This fixes PR24488.

Reapply "[SimplifyCFG] Be more aggressive" on branch_37

I have underestimated the importance of this patch, and
James has got a fix for it in the making. Sorry for the noise.

Revert "[SimplifyCFG] Be more aggressive" on branch_37

2015-08-20T15:05:48+00:00

This reverts commit r229099 in branch 37 only, because it caused PR24292.
I'll continue investigating and will fix on trunk, but being an optimization
change, we can let the rest of the release go without this one.

llvm-svn: 245568

Add release notes for the typeless pointer work.
