Jakob Stoklund Olesen 207cd4bbd7 Allow a register to be redefined multiple times in a basic block. 
LiveVariableAnalysis was a bit picky about a register only being redefined once,
but that really isn't necessary.

Here is an example of chained INSERT_SUBREGs that we can handle now:

68      %reg1040<def> = INSERT_SUBREG %reg1040, %reg1028<kill>, 14
                register: %reg1040 +[70,134:0)
76      %reg1040<def> = INSERT_SUBREG %reg1040, %reg1029<kill>, 13
                register: %reg1040 replace range with [70,78:1) RESULT: %reg1040,0.000000e+00 = [70,78:1)[78,134:0)  0@78-(134) 1@70-(78)
84      %reg1040<def> = INSERT_SUBREG %reg1040, %reg1030<kill>, 12
                register: %reg1040 replace range with [78,86:2) RESULT: %reg1040,0.000000e+00 = [70,78:1)[78,86:2)[86,134:0)  0@86-(134) 1@70-(78) 2@78-(86)
92      %reg1040<def> = INSERT_SUBREG %reg1040, %reg1031<kill>, 11
                register: %reg1040 replace range with [86,94:3) RESULT: %reg1040,0.000000e+00 = [70,78:1)[78,86:2)[86,94:3)[94,134:0)  0@94-(134) 1@70-(78) 2@78-(86) 3@86-(94)

Douglas Gregor 7dbfb46163 Canonicalize template template parameters when canonicalizing a 
template name that refers to such a parameter. It's amazing that this
problem didn't surface earlier. Fixes PR7387.

Jim Grosbach 2c8b829238 modify so the test doesn't drop an output file in the test source directory. 
The test should also likely have some FileCheck bits to validate the
output(?).

Caroline Tice d6ac38485b Parameterize the shell scripts for creating and copying the python and

Darwin systems.

Douglas Gregor 1c69bf00ae If a non-dependent base class initializer fails to match any direct or 
virtual base class, but the class still has dependent base classes,
then don't diagnose the failed match as an error: the right base class
might magically appear. Fixes PR7259.

Benjamin Kramer a13bd20396 simplify-libcalls: fold strncmp(x, y, 1) -> memcmp(x, y, 1) 
The memcmp will be optimized further and even the pathological case
'strstr(x, "x") == x' generates optimal code now.

John McCall e9cccd86da Fix a point of semantics with using declaration hiding: method templates 
introduced by using decls are hidden even if their template parameter lists
or return types differ from the "overriding" declaration.

Propagate using shadow declarations around more effectively when looking up
template-ids.  Reperform lookup for template-ids in member expressions so that
access control is properly set up.

Fix some number of latent bugs involving template-ids with totally invalid
base types.  You can only actually get these with a scope specifier, since
otherwise the template-id won't parse as a template-id.

Fixes PR7384.
