This patch adds basic support for MachO::load_command. Load command types and sizes are encoded in the YAML and expanded back into MachO.

The YAML doesn't yet support load command structs, that is coming next. In the meantime as a temporary measure when writing MachO files the load commands are padded with zeros so that the generated binary is valid.

Currently there is no reasonable way to control the warnings in the 'use' phase
of the IRPGO pass. This is problematic because the output can be somewhat
spammy. This patch adds some flags which allow us to optionally disable these
warnings. The current upstream behavior will remain the default.

Without a diagnostic handler installed, llc's behaviour is to exit on the first
error that it encounters. This is very different from the behaviour of clang
and other front ends, which try to gather as many errors as possible before
exiting.

This commit adds a diagnostic handler to llc, allowing it to find and report
more than one error. The old behaviour is preserved under a flag (-exit-on-error).

Some of the tests fail with the new diagnostic handler, so they have to use the
new flag in order to run under the previous behaviour. Some of these are known
bugs, others need further investigation. Ideally, we should fix the tests and
remove the flag at some point in the future.

*We don't currently handle the  edge case constants (min/max values), so it's not a complete
canonicalization.

To fully solve the motivating bugs, we need to enhance this to recognize a zero vector
too because that's a ConstantAggregateZero which is a ConstantData, not a ConstantVector
or a ConstantDataVector.

[CodeGen] Clang does not choose aapcs-vfp calling convention for ARM bare metal target with hard float (EABIHF)

Summary:
Clang does not detect `aapcs-vfp` for the EABIHF environment. The reason is that only GNUEABIHF is considered while choosing calling convention, EABIHF is ignored.

This causes clang to use `aapcs` for EABIHF and add the `arm_aapcscc` specifier to functions in generated IR.

The modified `arm-cc.c` test checks that no calling convention specifier is added to functions for EABIHF, which means the default one is used (`CallingConv::ARM_AAPCS_VFP`).

Summary:
The AST contexts are not needed in the server components, and the clang context in particular
pulls in large parts of clang into the binary. Simply removing these two calls reduces the
lldb-server size by about 50%--80%, depending on the architecture and build type.

This should not impact the client parts as the same calls are already present in
SystemInitializerFull.
